Heidi Klum had no problem baring her backside in an Instagram photo to her followers. The 40-year-old supermodel posted a photo of her toned derriere showing that she didn't apply the right amount of sunblock for her beach vacation with her boyfriend, Martin Kristen, and her kids. She captioned the cheeky photo "Ouch!"

The mom-of-four seemed to enjoy her 4th of July holiday as she was photographed frolicking in the crystal clear water in a colorful bikini with her hair pulled back in cornrowed ponytail. She shared snaps of her getting her hair done, which her young daughters also sported while on vacation.

While the "Project Runway" host was posting photos of her beach vacation, supermodel Gisele Bundchen posted her own photos on Instagram of her sharing an adorable moment with her daughter Vivian, E! News reports. The Brazilian beauty captioned the photo od her one-year-old baby "The best love in the world!"

Vivian is the second child for the model with her husband Tom Brady. The couple already have two other kids, Benjamin and John (Brady's son with his ex Bridget Moynahan). The Victoria's Secret Angel has already lost the baby weight as she prepares for her latest job as the face for Chanel's makeup line, Les Beiges. She told E! Online that she lost the baby weight by sticking to an intense exercise regime of kung fu and yoga.

She posted a message to her fans after giving birth to her daughter saying that she and Brady were excited to welcome another child into their family, Hollywood Life reports.

"We feel so lucky to have been able to experience the miracle of birth once again and are forever grateful for the opportunity to be the parents of another little angel. Vivian Lake was born at home on December 5. She is healthy and full of life. Thank you all for your support and well wishes. We wish you and your families many blessings."

Her husband is also enjoying some down time with the baby before the football season starts back up. He recently signed a three-year-contract extension with the New England Patriots.
