Ashley Greene and Vanessa Hudgens attend Oakley Bali Pro/Learn to Surf event

Starlets Vanessa Hudgens and Ashley Greene were spotted wearing matching black bikinis during Wednesday's Oakley Bali Pro/Learn to Surf event in Benoa, Bali, Indonesia.

Hudgens, most recently of "Spring Breakers" fame, 24, and the "Twilight" star, 26, where also joined by Hudgens's boyfriend, Austin Butler.

Hudgens hinted that she was going on a trip in a tweet she wrote on June 18. The post read, "Photo: Going on a lil adventure :)"

Both Hugdens and Greene looked incredibly fit as they surfed Indonesian waves. Asked about how she keeps her body in shape, the "Machete Kills" star told Us Weekly she does a little bit of everything.

"I try to shock the body as often as possible -- I think that's really important," she said. "I do Soul Cycle constantly, do a lot of Pilates, a lot of yoga for the mind, dancing, kickboxing, hiking. . . anything and everything!"

As for how the surfing session went, a photo of Grenne's bruised leg posted on her Instagram account says it all.

"War wound from surfing today with Oakley," the actress captioned the picture. "The reef ate me up. #worthit"
