Adorable couple Nick Jonas and Olivia Culpo celebrated New Year's Eve together, and unsurprisingly had a "blast" together enjoying the occasion.
The lovebirds rang in 2014 with some of their closest friends in Mammoth Lakes, Calif., a source reveals exclusively to E! News.
The musician and former Miss Universe spent the evening at the Underground Lounge for a Great Gatsby-themed glamorous soirée. The pals sipped on Ace of Spades Champagne and Magnum Grey Goose.
"Olivia and Nick had a private table with bottle service," the source said. "They were enjoying themselves, and everyone was respecting their privacy."
The couple spent the night dancing together and with their friends to tunes provided by well-known DJ's Remix Artist Collective.
"They seemed like a happy mountain couple," the source added about the duo, who spent several days before the holiday enjoying the beautiful scenery in the mountain location.
