Chrissy Teigen is still oozing with sexiness even though she's pregnant with her first child. The Sports Illustrated model and "The Fablife" co-host went braless as she prepared cinnamon rolls for the talk show's holiday party, People reported, and showed off major cleavage in two separate Instagram posts.

The 30-year-old uploaded a photo of herself wearing nothing but a black and gold striped blazer, a stacked gold chain necklace and a black high-wasted skirt. She showed off an insane amount of cleavage in the ensemble as she pointed down on her kitchen counter, where cinnamon roll dough was laid out with cinnamon and sugar sprinkled on top. She captioned the shot, "Cinnamon rollllllsssssss!!!"

Her second post was a short video clip, shot straight on at Teigen as she ladled a generous amount of frosting onto her freshly baked batch of treats. A sports game could be heard in the background, and Teigen sang playfully as she prepared the rolls while wearing a Santa hat.

"Oh baby, merry Christmas to us," Teigen sang, and the video's caption read, "Bringing some goods to the @fablifeshow holiday party!"

Hopefully Teigen's cinnamon roll recipe will be included in her new cookbook, titled "Cravings." The book is set for release on Feb. 23 and is currently the number one book on Amazon's pre-sale list, according to the Daily Mail.

The new mom-to-be just celebrated her 30th birthday, as previously reported by HNGN. Her R&B crooner husband John Legend threw her a surprise party and serenaded her with a rendition of "Happy Birthday."
