Justin Bieber has had an emotional 24 hours, to say the least.
The pop star broke down sobbing after his MTV Video Music Awards performance on Sunday night, and by Monday morning he released the super steamy music video for his new single, "What Do You Mean?" Going shirtless and turning up the sex appeal, Bieber makes out with his rumored girlfriend, model Xenia Deli, in the video.

"The story is passion love, about crazy love," Deli tells ET. "We love each other, but at the same time we hate each other."
Deli says that she has plenty of love for JB, but shuts down rumors that the two are an item.
"No, I am not dating Justin and I am not dating anyone else," she says. "We are just friends."

Make that friends who get super sexy together on-screen. At one point, Deli even licks Bieber's abs. But that's all in a day's work for the Victoria's Secret model.
"This is a job," she says, but "it was so much fun because he is such a nice guy, and he was making everything easy."
In their two days together on set, Deli says she saw no signs of Bieber's bad boy image. "Oh my gosh, he is different than we see him in the videos, or interviews or pictures," she says. "He is a gentleman. For me, it's very important and what I appreciate in men -- it doesn't matter how old you are, how much money that you get, what is your job, you have to be respectful to a woman and this is how Justin is."
And that includes his sensitive side -- Deli says she "just wanted to give him a huge hug" during that on-stage breakdown on Sunday.
