Nick Cannon Cast Mariah Carey's Dog Look-alike In 'Dream Girl' Vid

Exclusive Details

Mariah Carey is still Nick Cannon's dream girl ... at least she is in his latest music video, which features a diva doggie version of his ex.

Nick just dropped his Ncredible Gang vid for "Dream Girl" featuring Jeremih and Ty Money. We're told the song's definitely about Mariah -- Nick even sings "ain't over my ex." 

Gotta love the concept -- Nick got adorable pooches to stand-in for the humans. Mimi, Nick and even their twins, Monroe and Moroccan, have doggie doppelgangers. Nick's is easy to spot -- he's the one in a turban. And watch for the Migos cameos as chihuahuas ... with locks!!

We'll say it ... this is bitchin'.
