Add Lisa Rinna to the list of age-defying celebrities.
The Days of Our Lives star, who will celebrate her 50th (!) birthday in July, kicked off her wedding anniversary with hubby Harry Hamlin in Mexico earlier this week, looking smoking hot in a teeny bikini.
The couple's two daughters, Delilah and Amelia, joined them on their trip, which a source tells E! exclusively was a combined family vacay, spring-break getaway, and commemoration of Rinna and Hamlin's 16th anniversary.
During their trip, the family spent a lot of time at the beach, swimming with dolphins and snorkeling. They also visited the Maya ruins, and wined and dined at various restaurants on the Villa del Palmar beach resort and spa in Cancun, where they stayed in a three-bedroom penthouse.
"Loving Mexico....I don't want to leave!," Rinna tweeted Tuesday.
We don't blame her.
