The 40-year-old actor and 29-year-old actress jetted down to Mexico for a vacation south of the border last week.
The cute couple were snapped splashing around in the ocean and getting their PDA on in the pool at the Villa La Estancia Riviera Nayarit resort in Nuevo Vallarta. Alexander showed off her hot body in a tiny blue bikini. Facinelli looked equally sexy in short shorts that showed off his abs and legs.
According to a source, Facinelli and Alexander got a couple's massage at the resort's Tatewari Spa and jet-skied around Banderas Bay. They also had an intimate candlelit dinner on the beach to celebrate Facinelli's recent 40th birthday.
Facinelli returned home to NYC last Tuesday and Alexander left the next day.
Alexander isn't shy about showing off her fine physique. The brunette beauty's skin-baring bikini style conjures memories of her now-famous Thor: The Dark World premiere Azzaro Couture gown, which featured large sheer cut-outs that showed tons of skin!
