Nick Jonas Debuts Sexy 'Close' Music Video, Reveals He 'Can't Open Up and be Vulnerable With Someone'

The sexual tension is really building in this music video.

The sexual tension really builds between Nick Jonas and Tove Lo in his new music video for "Close."

The video begins with the musicians seated facing one another as they sing the catchy tune. Soon the clothes are coming off and the magnetic force of attraction causes them to get, well, close. However, the two barely touch in the video, even though at times their lips are mere centimeters away from each another.

The music video -- which is reminiscent of Sia's music videos with Maddie Ziegler -- falls right in line with the song's lyrics, which Nick admits is a very personal look at how he can be in relationships. "The first song you're gonna hear tomorrow night is about how I literally can't open up and be vulnerable with someone," he tweeted on Thursday night.

He further explained the emotions behind the music video and track when speaking to 102.7 KIIS FM's JoJo Wright. "It’s a song about feeling like you can’t be vulnerable with somebody," Nick said. "Feeling like you can’t let your walls down."

The 23-year-old singer -- who starts touring with Demi Lovato at the end of June -- also revealed that he'll be dropping a new album, Last Year Was Complicated, on June 10, and admits that it's greatly influenced by his love life. This is sure to fuel speculation that he's singing about his ex-girlfriend, Olivia Culpo, and his rumored romance with Kate Hudson.

Nick later shared via Twitter the tracklist for the album includes "Voodoo," "Champagne Problems," "Close," "Chainsaw," "Touch," "Bacon," "Good Girls," "The Difference," "Don't Make Me Choose," "Under You," "Unhinged" and "Comfortable."

"When I first started making [the album] I thought I knew what it would be about... Then I had a breakup," he tweeted. "It then became very clear what this thing would be about... And that I would need to dig really deep."

Nick added: "Sh** is too real sometimes... Reliving some of these real life experiences through this music is hard. ...But I know it's important that I do it. I want to be an open book in my art.."

Meanwhile, the "Jealous" singer's older brother, Joe Jonas, is also featured in a new music video that was released on Friday. The 26-year-old singer's band, DNCE, and True Grit star Hailee Steinfeld teamed up to debut the music video for their song, "Rock Bottom." The video chronicles the high and loves of being in a relationship, with Steinfeld appearing as a girlfriend that just can't seem to walk away from her guy, no matter how much they argue.

While we're certainly seeing a lot of Nick and Joe these days, we're not sure if all these new music projects will soon leverage a Jonas Brothers reunion. Check out this flashback of the brothers on the ET set in 2009:
