Angie Harmon shows off her killer bikini bod on her 45th birthday

Angie Harmon will not age.

The actress, who turned 45 on Thursday, shared a photo of herself on social media sunbathing while lying on a boat wearing a purple-and-white patterned bikini.

“Going for the best bday nap EVER… & then I couldn’t sleep. Afraid of FOMO!” Harmon wrote on the post.

Reaction was swift and enthusiastic.

Sharing swimsuit pics on her birthday seems to be a tradition for the mother-of-three — when she turned 41, Harmon treated fans to a photo posing in a bright red, cut-out one-piece swimsuit.

Harmon has clearly gained entry into the celebrity anti-aging club which is bursting with beauties.

For example, Halle Berry is 50-years-old and gave birth three years ago.

Elizabeth Hurley is 52 and eligible for an AARP membership.

At age 63, Christie Brinkley is almost retirement-ready and two years away from becoming an official senior citizen.

Suddenly, the future seems brighter. And fitter.
