Watch: Guetta & Usher on 'Ellen', Mary J. Blige Does 'The View', Avril Lavigne Visits 'Regis & Kelly'

Lyrics » Avril Lavigne » News

David Guetta and Usher stopped by Tuesday's episode of 'The Ellen Show' to deliver a new live performance of their smash hit collaboration "Without You" - As usual, the Frenchman oversaw everything from the DJ deck, taking the role of hype-man, while UshA was offering a pretty nice vocals showcase below. This party-ready tune keeps refusing to leave the Top 10 on both the Billboard Hot 100 chart and the American iTunes. Good for 'em, but I just wish people would once for all start moving on from this song, so all the spotlight could already begin falling on the Nicki Minaj-assisted "Turn Me On". Grrr!

Queen of Hip-Hop and R&B Mary J. Blige took the stage on Tuesday at 'The View' to treat their fans watching with a new rendition of her Drake-assisted single "Mr Wrong". Sadly, Drizzy is yet to be seen helping Mary out with a live gig. She killed though! After all these years, her crazy hot vocals remain intact.

On Monday (November 28th), Canadian pop star Avril Lavigne was seen performing an acoustic rendition of her latest single, the Max Martin-produced "Wish You Were Here" on 'Regis & Kelly'. I still like this song! Play it once in a while whenever I'm feeling down, lol. Btw, princess Avril slayed effortlessly! Good vocals.

What do YOU think of these performances?
