Miley Cyrus, 15, says the age difference between her and her 20-year-old boyfriend does "not really worry" her.

The "Hannah Montana" star refused to reveal details of her romantic involvement with underwear model Justin Gaston, but said she is very close to the long-haired hunk.

First there were rumors that Miley Cyrus was dating youngest Jonas Brother Nick. Now rumors are swirling that middle Jonas Brother, Joe, is dating country singing sweetheart Taylor Swift.

Even though Taylor, 18, has said that Joe is just a friend, he did turn up at her concert Sunday night in West Palm Beach, apparently without his brothers Kevin and Nick. Taylor was opening for Rascal Flatts at the Cruzan Ampitheatre.

Pink has denied "dissing" her estranged husband in her new video.

The "Stupid Girls" singer - real name Alecia Moore - is seen sawing down a tree bearing a love heart containing her and motocross star Carey Hart's names in the promotional clip for "So What" as she sings "I'm all right, I'm just fine and you're a tool."
