Demi Lovato/ Kelly Clarkson Collaboration In The Works?

Lovato -- whose Here We Go Again will be #1 on the Billboard albums chart next week -- has mutual admiration for Clarkson.

[artist id="3079280"]Demi Lovato[/artist] is having quite a summer. Not only is she on tour with "American Idol" runner-up David Archuleta, but the Disney star's sophomore album, Here We Go Again, will debut at #1 on next week's Billboard 200 albums chart.

She worked on the album, which sold 107,000 copies in its first week, with good friend Nick Jonas, as well as John Mayer, and those collaborations seem to have paid off. Her last album, Don't Forget, made its debut at #2 last summer.

"I can't believe it... I'm speechless... Seriously wow... Here We Go Again #1 album on Billboard's Top 200!!!" she tweeted. "Thank you guys so much!!!! I love you!!!!!!!"

If that weren't enough for the "Camp Rock" star, her music recently received accolades from [artist id="1231768"]Kelly Clarkson[/artist] at one of Clarkson's recent concerts. Lovato recently tweeted, "Oh. My. God. Thank You Kelly Clarkson!!!" after a video of Clarkson talking about the 16-year-old appeared online.

"She's really good," Clarkson shared with the audience. "She can sing her butt off! And I told her I'd get her CD and I already have it."

The admiration is mutual: Lovato recently told MTV News how much she'd like to work with Clarkson. She'd love to get her to make a cameo on her TV show, "Sonny With a Chance."

"I think it'd be really cool to have Kelly Clarkson on the show," she said. "And I've never seen her act on anything, other than her movie ["From Justin to Kelly"]. But I think it'd be really cool to work with her."
