As if Britney's awesome new album (hear it here!) isn't reason enough to be psyched for her tour to start in March, now you can look forward to her tour mates: the Pussycat Dolls! "We've just been working on it for a long time," Nicole Scherzinger tells Ryan Seacrest on his KIIS-FM radio show. "It's going to be a huge tour -- we just had to get on it. We're so excited!" Apparently, the Dolls have been buddies with Brit for a while now and Brit even shot a cameo for their video "When I Grow Up" earlier this year, but it was edited out of the final cut.

So what's Nicole most excited about on the tour? "The Pussycat Dolls can babysit Britney Spears' kids!" she told Ryan. Uh, how un-rock star of them…
