Among the throng of A-list Hollywood personalities that headed over to Las Vegas to ring in 2015 were Miley Cyrus and Patrick Schwarzenegger. No surprise there. The couple has been recently spotted jetting off from one location to another, arm in arm, ready to dance and party the night away.

 But after the young couple celebrated the arrival of the New Year with family, they were joined at the Planet Hollywood Resort and Casino with hot Hollywood twosome, Modern Family and Chef star, Sofia Vergara and True Blood hunk, Joe Manganiello.

 Vergara, who recently got engaged to her boyfriend Manganiello over the holidays after a Christmas jaunt in Hawaii, posted on her Whosay page to give fans a peek into their New Year's day-

 "Excited for the new year!!!!" the Modern Family star posted. "Wishing everyone a lot of work and happiness!!!)

The Hawaii trip also served to celebrate Manganiello's 38^th birthday with family and friends.

The Colombian beauty then posted a picture of herself posing with her fiancé, "Happy New Year!!!!! Feliz añooo."

Reportedly, the couples polished a sumptuous New York strip steak and black truffle creamed spinach and potato dinner before they all went and caught the sold-out Britney Spears Vegas concert, where they all got to meet the pop idol.

Eye witnesses say that the couples definitely looked like they were enjoying the evening. The newly engaged pair appeared very affectionate, constantly holding hands and whispering in each other's ears. And of course, their younger pals were apparently just as sweet as they partied for the New Year.
