Christina Aguilera is set to tour the US in support of her new album, Back to Basics, and she's giving her fans plenty of notice.

With a European tour that kicks off in the UK November 17, Aguilera today announced 41 stops at US arenas in the first part of 2007, kicking off in Houston February 20 and concluding May 5 in Sunrise, Florida.

Aguilera has tabbed two girl groups as opening acts. Danity Kane will open the shows, while the Pussycat Dolls will serve as the primary opening act. Aguilera was one of the group's guests when they were still performing as the Pussycat Doll Revue in Los Angeles.

Tickets for the US tour dates go on sale Saturday.

No word yet on Aguilera's much-hyped tour of US jazz/blues clubs.

"At a certain point, we are fitting in the more intimate blues/jazz club tour," she told MTV.com in September, "which I'm really excited about. It's going to be an amazing, amazing show that I can't wait to put on, but dates are to be determined for that whole shebang."
