Joe Jonas had "half" an erection while filming DNCE's steamy new video for 'Body Moves'.

The 27-year-old singer insists it would have been difficult not to be aroused while shooting the saucy clip with model Charlotte McKinney.

Writing as part of an AMA on Reddit, he admitted: "There was definitely some half chubbing going on during the video.

"I wouldn't say a full blown boner, but I would say a haflie.

"I mean it's kind of hard not to in that situation especially when you're trying to be intimate, and also they put us in an elevator, me and Charlotte McKinney who I'm sure Reddit is very familiar with.

"They put her in an elevator with me and then they had kind of a hidden camera filming this whole time, and I had a great time doing the video."

Joe was left shocked and baffled earlier this week when a fan arrived at his house with all her belongings and announced she was going to move in with him.

He said: "This woman was sitting outside my house in a car for a while and her car was completely full of furniture and clothes and my friend went up to the car to ask what was going on and she said that she was waiting for me and said that she was moving in and that she was waiting until I got home to start unloading her stuff from her car."

The 'Cake By the Ocean' hitmaker lives with his brother Nick and enjoys it because the 24-year-old singer-and-actor is away a lot - and he gets access to his younger sibling's wardrobe.

He said: "It's nice because he's been travelling and I'm home alone all the time.

"I get this nice sized house, just chilling.

"Also, when he comes into town, he came into town this past weekend, our housekeeper put a bunch of his new clothes in my closet and he left town to go finish filming 'Jumanji', so I don't have to go shopping. I just have a bunch of Nick's free new clothes now."

And when he does have time off, Joe is "addicted" to playing DNCE's own video game.

He admitted: "It's actually insane, I'm addicted to my own game. It tells me, 'Hey, would you like to buy more lives?' and I'm like... dammit, so pretty much am I paying myself?"
