Age is but a number to Jennifer Lopez.

The quadruple threat (singer-dancer-actress-producer), who turned 50 last month, is kicking back on a vacation with fiance, Alex Rodriguez, in St. Tropez.

The couple both shared several photos together from their romantic getaway on their Instagram Stories, but Lopez stole the show with a solo shot in a one-piece that read, "Forever Young."

It was revealed by the film's director recently that JLo took A-Rod to a strip club to prepare for her role.

Writer and director Lorene Scafaria told Vulture in July: "[Lopez] and Alex went and visited a strip club, and she was able to give me some… insights."

Scafaria said the Lopez used her supreme athleticism in a big way for her pole-dancing scenes.

"She’s obviously such an unbelievable dancer, but she trained so hard-core for this," Scafaria said. "Pole dancing is not like anything else. It required muscles you don’t know you have. So we did treat it a little bit like a sports movie in that way."
