Willis, 25, walked across the sandy beaches of the resort wearing neon, printed bikini bottoms and a black, bondage-inspired, strappy bikini top. She left her long red-hued locks down and peered confidently at her destination behind a pair of shades.
"I feel so lucky I got to start my new year off with my mom and a lovely group of friends," the actress shared via Instagram on Wednesday, Jan. 1, along with a picture with her 51-year-old mother. Moore and her daughter, both tan and healthy-looking, smiled for the camera in an outdoor setting of the tropical locale.
The two rang in the New Year along the sandy beaches on the Riviera Maya alongside Willis' on-again beau Jayson Blair and Moore's new, significantly younger love interest, drummer Sean Friday, 27.
While Moore created a stir -- first with her amazing, fit bikini body and later her new beau -- Willis has been catching up on beach reads and sleep. "This is what happens when you get stay up to late reading #orangeisthenewblack #vacationbook," she shared via Instagram on Thursday, Jan. 2, of herself nestled up beside a copy of Orange is the New Black.
