I think Janet has more #1s. Anyway, I consider MC the Queen of Crossover or perhaps music as a whole.

Queen: Mary J. Blige
Princess: Alicia Keys

Mary J. Blige.

Oh right, I forgot she existed because she hasn't had an actual hit since 2001

I'm voting for Invisible? by god! Invisible is past a long time a go!... And If you are fan of disney, you are fan of the main artist of them Horsey... and I'm not maniatic of Ashlee... I'm fan of her, I Like her songs and support her...

I know you aren't talking about having a bad album (Glitter, Charmbracelet). Yea didn't think so

Yeah. Ditto.

Nominees
1. Mariah Carey Comeback Queen maybe but R&B Queen, no.
2. Jennifer Lopez WTF?!? She's pop!
3. Beyoncé Not strickly R&B.
4. Alicia Keys Consider her as the Princess, not the Queen.

But Mariah and Mary J. Blige are also nice picks.

enough of this discussion

Rihanna, Ciara, Jennifer Lopez (Top 10 Pro-Toolers of All Time), and Ashitty should not even be nominated.

Mary J. Blige HANDS DOWN
Alicia keys comes a close second.

Now if this was R&B Divas, Whitney and Mariah

Actually my wife is not pop she is R&B and maybe even hip hop not to mention her song We Ride is #10 and SOS is #4 on R&B i-tunes right now!

Well enough ya!... you always begin this

MJB and Rihanna

Finally someone gets it right.

Either Mary or Janet.

Yeah she had some missteps, but let's see Janet sell 6 million copies of 20 YO.

Well Janet, Mariah, Madonna, and Whitney still have a lot to work on. They have yet to be inducted in the Rock & Roll Hall of Fame. Michael and Prince are already there. So they're certified legends already.
