Playing EXCLUSIVE: Watch Joe Jonas and Ashley Graham Make Out on the Set of His New Music Video

Things are getting steamy between Joe Jonas and Ashley Graham!

The happily married model does lock lips with the DNCE frontman -- but it's all for the sake of his new music video. Only ET was on the set of "Toothbrush," filmed in the O Hotel in Downtown Los Angeles, and spoke with the group about how the project came together.

"This is my first music video and I've been a fan since 'Cake By the Ocean,' which I can't get out of my mind," Ashley gushed to ET's Lauren Zima at the O's D'Vine Wine Cellar. "It's such a great song and they're such amazing, interesting people individually, and I'm just happy to be here."

After the massive success of the band's catchy debut single, Joe admits that DNCE -- rounded out by bassist-keyboardist Cole Whittle, guitarist JinJoo and drummer Jack Lawless -- has been "evolving creatively" with their new music. "Toothbrush" is featured on the band's EP, out now, while a full-length album is due in August.

"Toothbrush" is "just one of those songs that we felt really passionate about and really embodies what DNCE is," he said. "It's [about] that point in a relationship when it's starting to get a little serious, but you aren't fully there yet. Sometimes people leave a T-shirt or some shoes at somebody's place, this time we are talking about a toothbrush. ... It's a song about a beautiful moment in time and I hope everyone really enjoys it."

After going their separate ways professionally in 2013, Joe's younger brother, Nick Jonas, seems to be a huge fan of DNCE's music! The pair have performed the track together on-stage, and Joe couldn't help but deliver his signature Nick impression during ET's sit-down! See the hilarious moment in the video above.

Earlier this year, Ashley stripped down for a nude photo shoot with a little "support" from her husband, Justin Ervin. Now, the size-16 model says that her hubby has no problem seeing her steaming up the screen with a musician.

"You can't be with an insecure man if you're Ashley Graham!" she joked.

Sitting down with ET back in March, Ashley got candid about why she waited until marriage to have sex with her husband and how they keep their long-distance marriage strong. See the interview in the player below.
