AceShowbiz - Zac Efron is single and continues to mingle. The 36-year-old actor has been seen enjoying a yacht trip with Gerard Butler in St. Tropez, where they were surrounded by a bunch of scantily-clad women.

In photos obtained by DeuxMoi, the Ted Bundy in "Extremely Wicked, Shockingly Evil and Vile" appeared to be making acquaintances while aboard the yacht. He was photographed shaking the hand of a blonde beauty who was sitting in front of him.

Going shirtless and baring his chiseled abs, the "High School Musical" star seemed to be amused by the girl as he let out a smile while having a conversation with her. The former boyfriend of Vanessa Hudgens was also pictured helping another girl with long black hair open her bottled drink. Both of them looked wet, seemingly after playing in the water.

For the occasion, Zac ditched his shirt and wore a pair of blue swimming trunks. He occasionally put on his sunglasses and a black cap to protect him from direct sunlight. He also carried a drink in his hand while enjoying the view with Gerard standing next to him.

At another point, the two actors seemed to be browsing through something that Zac showed in his phone. As for Gerard, he rocked a gray T-shirt and dark shorts while accessorizing with aviator shades.

Prior to this, Zac was spotted partying with some beauties in St. Tropez. "The Greatest Showman" star was joined by two male friends and four fashionable women for a yacht outing in the picturesque coastal town. The group then dined at the elegant restaurant Loulou on Pampelonne beach.

Meanwhile, Gerard recently sparked romance rumors with much younger model Penny Lane. The 54-year-old actor was out and about with the 29-year-old model in London on July 3, strolling around the city together. They were also seen stopping by a restaurant, where the Sports Illustrated model was adoringly gazing at the "Olympus Has Fallen" actor and laughing during their conversation.
