Jessica Simpson channels Pamela Anderson in new photo

Jessica Simpson channeled Pamela Anderson in a new photo Wednesday.

The 35-year-old designer showed off her bombshell looks and plenty of cleavage in a swimsuit picture that sees Simpson strike a pose with her sunglasses on and blonde hair up.

Simpson has been vacationing in St. Barts since last week to celebrate her 35th birthday. She previously impressed fans with her toned body by sharing a leggy snapshot from the fête.

Husband Eric Johnson, children Maxwell and Ace, and several friends are also on the getaway. Simpson also posted a photo of her children in the water, while actor Dave Annable shared a picture of himself with the designer.

"30 friends on vacation celebrating this beauty @jessicasimpson. You are loved. Thanks for raising my street cred. Happy birthday. Love you. #yesimflexing," Annable wrote. His wife, Odette Annable, posted her own photo with the star.
