A Week In News Feat: Chris Brown, JK Rowling, Lady Gaga, Billie Joe Armstrong, Miley Cyrus and More

Brown nosing? How did Chris Brown get out of this one!? The 'Stop It' hit-maker has tested positive for cannabis while on probation, though Judge Patricia Schnegg said that she had never warned him against using drugs so couldn't punish him further. However, she did order a review of his community service hours following some discrepancies.

Potter returns? Though she's just about ready to release her first novel for adults, JK Rowling has given Harry Potter fans everywhere a little bit of hope after suggesting she may not be done with the famous boy wizard just yet.

The Ugly Society: Lady Gaga has defiantly hit back at those who criticized her recent weight gain, telling fans that "it's society who's ugly". The jibes came just days before Gaga was branded a "slut" by New York Politician James Molinaro - rough week huh?

21st Century Breakdown: Green Day frontman Billie Joe Armstrong was carted off to rehab this week after suffering an on-stage meltdown during the band's set at the iHeartRadioMusic Festival in Las Vegas. We certainly wish the veteran rocker all the best in his recovery!

Can't Be Tamed: Armed with her sharp new hairstyle, Miley Cyrus has taped her special-guest appearance on 'Two and a Half Men'. Those privy to the shoot - including actor Jon Cryer - say the singer/actress did a great job as a flirty friend of Ashton Kutcher's character!

Bynes Behind Bars? Amanda Bynes is certainly making all the right moves to get herself banged up. The actress was charged with driving with a suspended license last week, marking the third time that she's been in trouble with the law in recent months.

Don't Speak: No Doubt are letting all their music do the talking upon their return to the business. Their sixth studio album 'Push and Shove' isn't radically different to the groups' early material, though that's just the way their fans will like it, and the critics have warmly received the record.

Rihanna Returns: The Bajan singer has churned out hit after hit in recent years, and it looks as though her next single 'Diamonds' will continue that trend. The singer unveiled her latest offering this week - her 21st single release in three years!

Jake Snags No.1: It's a big congratulations to Jake Gyllenhaal this week, who heads the cast of crime-drama 'End of Watch', the new U.S. box office No.1. Made for just $7 million, the gritty cop movie pulled in over $13 million to top the chart ahead of Clint Eastwood's 'The Trouble With the Curve.'

Video of the Week: This week's hottest footage from New York, where Lana Del Rey arrived at the H&M concert, signing autographs and posing for pictures with fans. The appearance came in the same week that she debuted her new single 'Ride'.
