Jessica Stroup & Tristan Wilds: Beach Scenes for '90210'

Jessica Stroup chats with Tristan Wilds while filming for 90210 on Friday afternoon (December 14) in Huntington Beach, Calif.

Decked out in a full wetsuit, Tristan, 23, just came in from the surf for his scenes with Jessica, 26.

Earlier in the week, Jessica walked the carpet at the Charity:Water gala in New York City.

“After taking a trip to Ethiopia last year, I know our efforts will make an impact. I was really impressed to see that 100 percent of the donations are going exactly where they’re needed,” she shared inside the event.

So where’s she headed for her own vacation: Costa Rica! “I’m only packing swimsuits! And scripts for the show, of course.”
