Skylar Grey Performs on "American Idol" Tonight; will do "Coming Home" with Diddy

I don't usually watch "American Idol," but may tune in tonight to see the appearance by the young singer/songer/producer Skylar Grey, who I wrote about (and first heard of) at the Grammys last month. She co-wrote Eminem's "Love the Way You Lie" and "I Need a Doctor" those songs with Eminem and Dr. Dre on the Grammy telecast. She turned a lot of heads with her Grammy appearance, and sent many viewers off to Google to find out more about her.

Skylar Grey's profile will get another huge boost tonight when she's scheduled to be a guest on "American Idol" tonight, along with Diddy-Dirty Money and past "Idol" winner Adam Lambert. She is set to perform another song she co-wrote, "Coming Home," with Diddy (UPDATE: you can see the video above). Skylar Grey has been getting more attention in the press lately, too, including a profile in Billboard and a story in USA Today.

Speaking of "American Idol," apparently alt-country singer-songwriter Ryan Adams got some exposure on the show last night when contestant Paul McDonald sang his "Come Pick Me Up." And yes, "Ryan Adams" became a trending topic on Google last night. One person who needs to learn more about Adams is "Idol" judge Jennifer Lopez, who said on the show that she didn't know the song and hadn't heard of the singer.

You can see McDonald performing the abbreviated version of "Come Pick Me Up" from the show below.
