Miley Cyrus appears in Big Sean's new music video for "Fire," and she looks hotter than ever.

So why pick a 20-year-old former Disney starlet to sex up his latest vid? Sean tweeted, "[It's] a special video for a special song. I got Miley Cyrus for this video because she's somebody who's had a personal evolution as a lot of us have had. Besides all the personal stories I tell in the song, there are so many other ways people can make it through the fire."

He added, "I think Miley did a great job as a metaphor for strong women, being strong person after heartbreak (hence the burning pic that could symbolize her old romance), or maybe even deeper problems but in the end remaining as elegant as a rose. It's a cool visual that has a cool concept and meaning to it."

Wait, heartbreak? Is he referring to something going on with Liam?!
