It's no secret that Nick Jonas and Olivia Culpo are one of the cutest couples in Hollywood these days. The former Jonas Brothers member and Miss Universe 2012 have been spending a lot of time together and it looks like their relationship is only getting more serious.

The two of them have been making many public appearances together and most recently looked adorable together on the red carpet for the 2015 Billboard Music Awards. Jonas and Culpo arrived together at the MGM Grand Garden Arena on May 17 in Las Vegas and they looked hot, which comes to no surprise.

Culpo looked sexy in an Elie Saab jumper, Giuseppe Zanotti shoes and Norman Silverman jewelry while Jonas wore a full Kenzo suit.

Jonas attended the show to perform his single "Jealous" live on stage while his girlfriend supported him.

The former Jonas Brothers member was recently grilled by SNL's Vanessa Bayer for her joke web series Sound Advice and during their talk she apparently insulted his girlfriend.

The comedian fired some awkward questions and insults at Jonas, which also aimed at his relationship with Culpo.

While dressed up as a fictitious media coach Janessa Slater, Bayer said, "The Miss Universe thing is like bulls***, right? Like have you seen 'Guardians Of The Galaxy?'"

With a confused look on his face, Jonas asked, "How does that connect?"

"I just feel there's no way your girlfriend is hotter than those blue and green ladies," Bayer jokingly stated. "I'm not getting you to s**t talk your girlfriend, Miss Uni-don't!"

However, Jonas was a good sport about the jokes and took no offense to the comments. Bayer also poked fun at his hit single "Jealous" saying, "One of your new songs is titled 'Jealous.' And I feel like people must have a lot of sympathy for someone who's dating a former Miss Universe."

The host then jumped to the realization that Jonas wasn't "wearing a promise ring anymore."

Jonas previously admitted that he left his celibate days behind and told UK's Loose Women earlier this year, "It's important for anyone to grow, the thing that was strange for me was the emphasis on my sex life at 14, it's a crazy thing."

In the mean time, Jonas recently announced a bunch of dates for his upcoming tour.
