American Idol News: Adam & Kris Feud? Slash Loves Adam! Paula Sings

What's up with this rumored feud between Adam Lambert and Kris Allen? Who has more grooming products on the bathroom counter in the mansion? Who doesn't know how to take pictures with fans? And whose face hurts from smiling for the cameras all the time?

Wonder no further. We nabbed those answers and more when E! News caught up with American Idol's fab four finalists—Adam Lambert, Kris Allen, Danny Gokey and Allison Iraheta. Check out the video above to get the scoopage. But to get caught up on all of this week's Idol happenings involving Paula Abdul, No Doubt, Slash and more, read on...

Slash Digs Adam: Slash, former Guns N' Roses guitarist and currently with Velvet Revolver, is the guest mentor for tonight's classic-rock-themed performance show, where Adam, Danny, Kris and Allison will not only perform individually, but they're rumored to be doing duets as well. Slash hit Twitter last night and tweeted this: "Those A.I. kids can sing their asses off, especially Adam."

Paula Performs Live: Along with the reunited No Doubt and Idol alum Chris Daughtry, Paula Abdul will perform for the first time on the Idol stage on Wednesday's results show. She'll be belting out her new single, "I'm Just (Here for the Music)." Paula told E! News: "I wasn't sure I wanted to at first, but then I thought why not? I really think this song is a fun song. It's catchy, and it's a dance anthem." (Watch E! News for more from the Paula interview.)

Paula Picks Adam: The "nice" judge also told E! News who she thinks will take home the American Idol crown on May 20. "In the first auditions, I called Adam the winner. I think Adam is light-years ahead of the contestants that we've had, but we have unbelievably talented vocalists. Adam doesn't have to win. He's still going to be out there selling records for a long time. Meanwhile, Paula opened up to Ladies' Home Journal about withdrawing from pain medication last year. And she debuted her new single, "I'm Just (Here for the Music)," on Ryan Seacrest's KISS-FM show this morning. Read all about that and listen to the new single here.
