Before the actual baby photos and big baby bump arrives, the baby announcements are made, and celebrities seem to come up with the cutest ways to reveal to the world that they're expecting. Most took to Instagram to share photos with their significant other or teeny tiny baby bumps before people started making assumptions, while others waited until the time was just right and they already had a huge belly to show off.

With so many celebs getting pregnant this past year, it was hard to choose the most adorable announcements as everyone came up with such clever and heartwarming ways to share the exciting news, but here's what we think were 10 of the cutest pregnancy announcements of 2015!

Macklemore and Tricia Davis

Rumors started to go around that the "Thrift Shop" singer and his wife (who was still his fiancé at the time) were expecting their first child together early in January when Davis was seen at a party not drinking, as HNGN previously reported. The two decided to take matters into their own hands on Jan. 3 by confirming the rumors with a heartwarming video announcing the pregnancy.

"We wanted to share the news with you ourselves. Love Ben & Tricia" Macklemore tweeted at the time along with the link to the emotional video of the two at their first ultrasound appointment finding out they were going to be having a baby. Davis eventually gave birth to their baby girl Sloane Ava Simone Haggerty on May 29, and the two then got married on June 27 when the Supreme Court ruled same sex marriage legal nationwide.

Justin Timberlake and Jessica Biel

For months, rumors about this power couple expecting a baby were also going around, but it wasn't until January that they finally confirmed what everyone had been waiting for years to hear, and they made the official announcement with one of the cutest pregnancy photos ever.

"Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER!" Timberlake captioned a photo of himself kissing Biel's already growing baby bump. "CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets." The happy couple welcomed their first child, a baby boy, Silas Randall Timberlake, on April 11.

Leah and Brandon Jenner

The son of Caitlyn Jenner and his wife announced that they were expecting their first child together with a beautiful photo back in March. "Well, it's time we share the good news," Leah captioned the photo of Brandon cradling her tummy and kissing her cheek. "We're having a baby." The happy couple welcomed their baby girl Eva James on July 22.

Kristin Cavallari and Jay Cutler

The former reality star and Chicago Bears quarterback announced that they were expecting their third child together on her official app back in May with an adorable photo of the mom of three with her two sons Jacson Wyatt, 1, and Camden Jack, 2, in a wheelbarrel behind her and her hands over her tummy in the shape of a heart.

"We're at it again!" Cavallari, 28, wrote. "Thrilled to announced baby number 3 is on the way! The cutler crew just keeps on growin'!" She gave birth to her daughter, Saylor James Cutler, just last month on Nov. 23.

Ivanka Trump and Jared Kushner

The 33-year-old businesswoman and daughter of Donald Trump announced that she and her husband were expecting their third child together with an adorable photo shoot of herself and their two children Arabella, 4, and Joseph, 2 in September.

"I couldn't be more thrilled to share the news with you that I am expecting!" she wrote on her blog. "Arabella and Joseph are both incredibly excited to have a new sibling on the way. I consider myself incredibly fortunate to have a career that I am deeply passionate about, but, at the end of the day, it's my family that is at the center of my life - and to be adding another baby to our family is a tremendous blessing. Jared and I are so thankful, and so excited!"

Allison Holker and Stephen "Twitch" Boss

These two pro dancers made an extra special pregnancy announcement on live television during "Dancing With The Stars" in October. While waiting to perform with her partner Andy Grammer, Holker brought out her husband and 7-year-old daughter Weslie to share their exciting news for the "DWTS" Most Memorable Year night. "As a pro, 'Most Memorable Year' really is such a special time because we get to celebrate someone's beautiful story and share it with the world" Holker explained. "2015 is actually turning out to be such a memorable year for us because we actually recently found out that I'm pregnant!"

She then posted a photo of them after the show writing, "We are so happy that we were able to share our BABY news with everyone. Our family is over joyed with all the love and support we have received. This is such a special time for our family, our Baby Boss has already brought us so much light into our lives, That I am so excited to see what each new day brings!"

Chrissy Teigen and John Legend

After opening up about their pregnancy struggles earlier this year, the 29-year-old model and the 36-year-old singer happily announced that they were expecting their first child together in October with a black and white photo.

"John and I are so happy to announce that we are pregnant," Teigen captioned the adorable shot. "As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family. We're so excited that it's finally happening. Thank you for all your love and well wishes. I look forward to all the belly touching!"

Dwayne "The Rock" Johnson and Lauren Hashian

The actor waited until his longtime girlfriend was pretty far along in November to announce that they were expecting their first child together, but they did so with an extremely heartwarming photo, and announced the gender at the same time. "I was raised by and live with amazing and strong women, so the universe felt we needed one more," he captioned a photo of the two with his ginormous hand on her growing bump. "IT'S A BABY GIRL!! THANK YOU guys so much for the awesome support and love you've sent @laurenhashianofficial and myself from around the world. We're so grateful for this blessing and thrilled to share the news with y'all."

She then posted the same photo just two weeks ago writing, "I know I'm late to the party...Sometime life gets full and busy in the best ways. So grateful and in awe of this time. To experience creating a little life is just incredible. This beautiful cycle of life and womanhood beginning again. And like Big Daddy says-Couldn't be prouder of all the kickass women she's going to have around her. And men of course." Hashian gave birth to their baby girl Jasmine on Dec. 16.

Catherine Giudici And Sean Lowe

The "Bachelor" favorites announced earlier this month that they're expecting their first child together after getting married almost two years ago. "It's happening!" Lowe captioned a photo with his hand on his wife's tummy. "I'm going to be a dad!" She then shared a similar black and white photo simply writing, "Hey baby."

Chelsea Clinton and Marc Mezvinsky

The daughter of Hilary and Bill Clinton and her husband announced that they were expecting their second child together just a few days before Christmas with an adorable photo of their daughter reading a book titled "Big Sisters Are The Best."

"Next summer, Charlotte is going to be a big sister!" she tweeted. "Feeling very blessed & grateful this holiday season." She then shared the same photo on Facebook adding, "Being Charlotte's parents has been the most joyous, meaningful and loving experience of our lives and we are very excited about growing our family in the new year."
