The 'Burlesque' Premiere And The Beatles On iTunes In Today's Tweet Dreams

We were all over the "Harry Potter and the Deathly Hallows: Part 1" premiere last night, but it wasn't the only flick to roll out the red carpet. Christina Aguilera and Cher's upcoming movie musical "Burlesque" had its world premiere in Los Angeles on Monday evening, and those who attended seemed to love the film's glitz and glamor. Kristin Cavallari raved, "Burlesque was very entertaining. Christina is amaaaazing!!! And the makeup is I wanna dance." Khloe Kardashian tweeted after the screening, "OMG!!! Wow!! I can't say one bad thing about Burlesque! That was amazing! Congrats to all the amazing dancers, actors, singers!"

But it wasn't just the tunes from "Burlesque" that had the stars singing today. The Beatles are officially available for download on iTunes, and Hollywood charged up their iPads for the historic day. Actress Alyssa Milano tweeted, "SO AMAZING! The Beatles. Now on iTunes?" as singer Michelle Branch informed, "I just bought The Beatles box set on iTunes (even though I basically have everything anyway) Now I know what I'll be listening to all day :)" Meanwhile, the Dixie Chicks took a cue from the cast of "Glee" and asked followers, "The Beatles have joined #iTunes. If you were creating a Dixie Chicks/Beatles mash-up, which 2 songs would you mash together?"
