Nick Jonas must be one of the luckiest people on the face of the Earth. Not only has he been gifted with good looks, a good singing voice and bags of talent, but he has also managed to bag himself one of the most beautiful women on the planet as his girlfriend.

Nick Jonas has turned 21
It was rumoured for a while that Nick Jonas and Olivia Culpo were dating and, while it did take a while before either of them mentioned it, it is official that they are a couple. Olivia Culpo is the Rhode Island beauty, who won the Miss USA 2012 title, before going on to win Miss Universe 2012.
Nick Jonas turned 21 earlier this week and decided to celebrate his big day with his latest girlfriend. The couple enjoyed the celebrations along with the rest of the Jonas Brothers, as Kevin Jonas and Joe Jonas were also there, along with Kevin's wife Danielle Jonas and Joe's girlfriend Blanda Eggenschwiler.

The gang headed to Botero at Encore on Sunday evening, where they were joined by a group of around 25 friends and family members. The party enjoyed a nice meal on the patio, which included steaks, truffle macaroni and cheese and much more. Then, at the stroke of midnight, Nick Jonas officially turned 21 and the celebrations really began, with gifts and plenty of cake, before partying into the early hours.
