The 26-year-old Twilight actor played around at the pool later in the day and even tossed chef Seth Levine into the water!
Kellan recently told MTV that he helped his co-star Robert Pattinson buff up for Breaking Dawn!
“I’m really proud of Rob for working out and really training really hard. He cycled so hard and trained very hard, and he’s really diligent. He talked to me about what proteins to drink and what to do and he listened and cared. He had a great mentality for it,” Kellan said.
