David Guetta 'Had A Blast' Filming With Web Sensation Keenan Cahill

Dance-music superstar makes the trip to Chicago to shoot 15-year-old's latest lip-synching video.

When will David Guetta begin recording with U2? We can't confirm just yet, but on Tuesday (January 25), the French hitmaker added yet another name to an already stellar list of collaborators. Only this time, he's not pairing up with Akon, Black Eyed Peas or Madonna, but Internet sensation Keenan Cahill.

In just over a year, the Chicago 15-year-old has become a Web phenomenon by filming himself lip-synching pop songs from his bedroom. Ke$ha, Usher, Willow Smith, Lady Gaga, Rihanna and Pink are just a few artists who have gotten the Cahill treatment; his deliveries of "Like a G6," "Only Girl (In the World)" and "DJ Got Us Fallin' in Love" have more than 7 million views. Thus far, his version of Katy Perry's "Teenage Dream" is the most popular, with more than 27 million views.

Late last year, Cahill appeared on "Chelsea Lately," where the bespectacled teen gave host Chelsea Handler his digits and premiered his clip of 50 Cent and Jeremih's "Down on Me," in which Fif appears. He also appeared on MTV's New Year's Eve special donning 2011 shades in a vid set to Pink's "Raise Your Glass."

Cahill premiered his latest achievement, featuring David Guetta, on Tuesday, set to a medley of Guetta's hit songs ("Sexy Chick," "Memories," "When Love Takes Over," "Gettin' Over You" and his BEP classic "I Gotta Feeling"). When MTV News caught up with Guetta last week, he had just returned from Chicago after filming the clip with Cahill, and was still beaming from the experience.

"I had a blast," Guetta said. "I went to Chicago, and we just shot that video. It's really cool. It's really funny, and he's a really clever kid. Keenan is really a YouTube phenomenon. It's unbelievable. He's only 15, and he really knows what he's doing. His expressions are really funny and interesting."

Guetta described a bit about what happens in the clip.

"I was behind him. Sometimes I was there, sometimes I wasn't. It was about him, really. I think that's better like that," he said. "I just wanted to show support, and I thought it was a cool thing. I'm sure people are going to love this."

And if Cahill weren't big enough already, Guetta certainly knows a place where he is set to become a whole lot more famous.

"I'm sure people are going to love this. Probably, he's going to become really big now in France," Guetta laughed.
