Carole Middleton is one helpful mom. Kate Middleton's mother has reportedly been helping her daughter and grandson Prince George settle in, letting them stay at her Berkshire mansion for three weeks right after his birth and then going with them to north Wales when they moved, according to the Daily Mail. After weeks of rumors claiming Jennifer Lopez will return to "American Idol" as a judge, the singer's boyfriend, Casper Smart, said the buzz is true. "Yes," Casper told E! News, when asked if Lopez would rejoin the Fox reality singing competition for Season 13. According to E!, Casper thought the network had already made the announcement. Ooops. Justin Bieber has apparently remixed one of Michael Jackson's final songs to include his own vocals! Slave to the Rhythm was reportedly recorded by MJ just before his tragic death in 2009, but the release of the song in 2013 is something MJ certainly wasn't planning. What a music moment!
