Well, it looks like all of the Jonas Brothers are off the market. The youngest sibling, Nick Jonas, is allegedly dating Miss Universe Olivia Culpo and there's proof to all the talk. Here's all there is to know about Nick Jonas' lovely girlfriend.

Following Nick Jonas' tweet of a Mr Universe worthy body last week, it's not the least bit surprising that Nick would date an equally fit and lovely woman worthy of being called Miss Universe. The Jonas Brothers' youngest member is reportedly dating the current reigning Miss Universe, Olivia Culpo.

Nick and Olivia were first spotted together as co-hosts for the 2013 Miss USA Pageant. They were once again caught together as a romantic dinner last Thursday at the Ovest Pizzoteca in New York City. A source reports to E! news all the juicy titbits of the date.

"Nick was leaning in towards her across the table like she was saying something really important," reports the eyewitness., adding, "They looked really happy when they walked together. Me and my friend both agreed they were, like, swinging their arms all happily."

Prior to the dinner date, Nick and Olivia were said to be seen leaving Nick's apartment holding hands. Representatives of Nick Jonas have yet to speak up on the matter. Still, if the rumours were true, Nick Jonas definitely has caught quite a catch in Olivia Culpo.
