A Week in News Featuring: Demi Lovato, Britney Spears, Sacha Baron Cohen, Lady Gaga, John Travolta and More

The Final Four: What a week in showbiz. Just when American Idol and The Voice thought they were the biggest singing contests in town, Simon Cowell calls upon his secret weapon - or is that weapons? At a press junket in New York, the music mogul unveiled his new judges for The X Factor USA, Demi Lovato and Britney Spears - now you can't get much bigger than that, can you?

Wisteria Lane shuts its gates for good: As Cowell's show refuels for another season, the best-loved drama Desperate Housewives wrapped up after eight seasons on Sunday (May 13, 2012). Despite rumors of infighting, the cast can take solace in the fact that they've been part of one of the most watched shows in recent memory.

Has Jenny had enough? As the X-Factor USA gears up for a new season, and The Voice continues to grow in popularity, American Idol could soon find itself left behind. Fox bosses have already spoken of tweaking the format, but now Jennifer Lopez has thrown her future into doubt!

Hollywood Royalty Descend on Cannes: The richest and most famous movie stars in the world have begun descending on Cannes this week for the annual film festival. Though Brad Pitt's action-drama 'Killing Them Softly' and the Robert Pattinson movie 'Cosmopolis' are up for the Palme d'Or, we'd tip Wes Anderson's latest indie flick 'Moonrise Kingdom' to cause an upset!

Sacha Baron Cohen Gets the Hump: One man already stealing the headlines at the festival is Sacha Baron Cohen - or should we say his 'Dictator' character General Aladeen. The British actor arrived at the star-studded event on the back of a camel, but, er, had a little trouble dismounting.

Gaga Fights For The Right To Party: You didn't think Gaga would let the stars of Cannes take all the attention this week did you? Thousands of miles away in Asia, the singer is admirably fighting back against the Islamic hardliners and police force who have cancelled her concert in Jakarta. With 50,000 tickets already sold, we predict Gaga may win this battle.

John Travolta Puts Massage Troubles To Bed: Fans of John Travolta were thrilled this week, when the anonymous masseur attempting to sue him came clean and dropped the case. The actor can now concentrate his efforts on preparing for his role in the crime-drama 'Gotti: In the Shadow Of My Father', and we for one can't wait!

Video Of The Week: It didn't take us long to decide on this week's hottest footage! It comes from the Fox Upfront Presentation at the Wollman Rink, New York City, and features Britney Spears, Demi Lovato, Simon Cowell and LA Reid - not got it yet? Of course, it's the unveiling of the new X-Factor USA judging line-up. Check out Demi's lavish dress, which has been the talk of Twitter this week!
