David Guetta

What do you get when you mash up two of the best pop vocalists on the planet with one of the world's highest-profile DJs? You get this awesome mashup of Kelly Clarkson's 'Dark Side' with David Guetta and Sia's radio smash, 'Titanium.' The DJ behind the mix is Monique Kim, who dubbed the track 'My Stronger, Titanium, Dark Side.'

Claws out and paws up, pop people. It's Gaga vs. Guetta.

Maroon 5 are no longer leading PopCrush's Top 20 Songs for the week of Aug. 6, 2012, but they've been bumped to the No. 2 spot by a worthy competitor -- Katy Perry. Her tune 'Wide Awake,' which is one of our Top Songs of 2012, is now the No. 1 track on our Top 20 countdown.

'Titanium,' DJ extraordinaire David Guetta's collaboration with eccentric Australian songstress Sia, was such a smash success that it's no wonder he'd want to work with her again -- and now we know he has. During his set at Belgium's Tomorrowland festival, Guetta debuted the pair's latest effort, 'Falling To Pieces.'

David Guetta recruited some A-list talent for his song 'I Can Only Imagine' in the form of Chris Brown and Lil Wayne, and both artists appear in the futuristic video for the song. You'll be stepping into a sci-fi mini film -think a new version of 'The Matrix'- for the space of four minutes, thanks to trio.

David Guetta is continuing his reign as the DJ who releases the catchiest songs, and his next single 'I Can Only Imagine' featuring Chris Brown and Lil Wayne is no different. The three stars filmed the video on six -- yes you read that right, six -- different sets and even used face mapping technology to get the futuristic feel.

DJ David Guetta has worked with some of the industry's top voices (Usher, Jennifer Hudson, and Nicki Minaj just to name a few), so it's no surprise that he has broken the record for the longest charting dance hit in the past 10 years.

'Without You' was such a huge success for Usher and David Guetta that the performers have decided to work on new music together. Guetta confirmed The Hollywood Reporter's inquiry about whether he's planning to team up with the R&B star again.

Despite the fact that follow Young Money recording artist Nicki Minaj has collaborated with French DJ/producer David Guetta, don't expect Drake to follow suit. The Toronto-bred rapper is not a fan of fist-pumping dance music.

Some of the star power that made David Guetta's 'Nothing but the Beat' a success was on hand during the DJ's headlining set at Coachella. R&B star Usher joined Guetta on stage during Saturday's late-night set at the festival.
