Christina Aguilera will be back on the tour circuit, after taking time for her son Max, to promote her new album Bionic, and she promises fans she’ll wow them. She’s also slated to appear with Cher, Kristen Bell and Stanley Tucci, Eric Dane, Julianne Hough (Dancing With the Stars) and others in the film Burlesque, which opens Nov 24th. Tickets for Christina’s tour go on sale Thursday. You can listen to tracks at her MySpace page.

Saturday Night Live cast member Will Forte has let it all hang out for the camera, as part of a promo stunt and fake back story for his new comedy MacGruber, based on the ongoing SNL skit. As in completely naked, so when you click on this link for the uncensored photos, be warned. MacGruber may have a small penis — as in really small, as per the back story — but Forte has big balls for doing this photo shoot. The comedy opens this week and boasts Kristen Wiig, Val Kilmer as the villain Dieter Von Cunth, Ryan Phillippe, Maya Rudolph, WWE wrestler Chris Jericho and others.

On the other hand, some people don’t have the brass ones. One-time presidential hopeful John Edwards is afraid of jail and said to be trying for a misdemeanor plea for alleged campaign violations. The investigation by the FBI and IRS is trying to determine whether he paid his mistress, Rielle Hunter. Was she worth it, John?

Jonathan Rhys Myers, who recently got himself banned from flying United Airlines for an alleged display of drunkness and racial slurs, is going into rehab. I hear Celebrity Rehab with Dr. Drew needs cast members for the next season.

Guns’n'Roses frontman Axl Rose, whose brith name is William Bruce Rose but legal name is William Bruce Bailey, is claiming that music mogul and film producer Irving Azoff has been sabotaging the band in order to force Rose into reuniting with former band members. Other claims: that Azoff has been vicious by using Rose’s real name — something that Rose says carries a lot of emotional baggage. I guess changing your name to Axl Rose, an anagram of “oral sex,” was a better choice.
