Nick Jonas and Olivia Culpo Catch Some Rays in Oahu

Taking a bit of a spring break, Nick Jonas and Olivia Culpo lounged at the Kahala Resort in Oahu, Hawaii on Sunday (March 16).

The youngest JoBro rocked some black and white patterned swim trunks and a sleeveless black shirt while his girlfriend wore a white long-sleeved cover-up over her bikini.

It wasn't all fun in the sun for the 21-year-old musician, however, as he was in town filming for the CBS show "Hawaii Five-0."

Reprising his role as computer hacker Ian Wright, this is Nick's second appearance on the show. On Monday, he tweeted, "That's a wrap on @HawaiiFive0CBS."
