Mariah Carey has just announced an April 7 show in Toronto -- the first time the R&B-pop superstar has ever played in our town, if you can believe it.

It looks as if it will be an Air Canada Centre gig, although neither the venue, concert promoters or Carey's record reps could confirm anything yesterday.

But the 20,000 seat arena has been the venue of choice for fellow divas Cher, Celine Dion, Shania Twain and Jewel since it opened last February, so why would Carey be any different? Unless she wanted to tackle SkyDome. (Yikes.)

The Toronto date -- announced by Carey herself on MTV this week -- is one of nine North American shows making up her first dates on this continent in the last seven years.

The tour, in support of her latest album, Rainbow, begins March 16 in L.A. and wraps up April 11 in New York. The other dates are Las Vegas (March 18), Dallas (March 22), Chicago (March 25), Miami (March 29), Atlanta (April 1), Boston (April 4).

Carey, who picked up the Award Of Achievement at the American Music Awards earlier this week, is currently gearing up for a small European tour that begins Feb. 14 in Antwerp.

She told MTV some of the guests on Rainbow may show up on her North American dates.

"When I'm in the States, I'm going to see who's around whatever city we're in," Carey told MTV News. "Hopefully, in Atlanta or Chicago, maybe we'll have Da Brat. I haven't asked her yet. I have to give her a call and see what's up with her. I was paging Jermaine (Dupri) last night. He said he'll be there."
