Pop star Lady Gaga is begging her fans’ forgiveness after announcing yesterday that she has been forced to postpone four dates on her current Born This Way Ball tour due to synovitis, or severe inflammation of the joints. The shows postponed include scheduled concerts tonight and tomorrow in Chicago, Saturday in Detroit and Sunday in Hamilton, Alberta, Canada. Gaga said in a press release: “I am completely devastated and heartsick. I’ve been hiding this injury and pain from my staff for a month, praying it would heal… To the fans in Chicago, Detroit and Hamilton, I hope you can forgive me as it is nearly impossible for me to forgive myself right now.”

The man who crashed the stage at the Grammys when Adele won her award for Best Pop Solo Performance was arrested for trespassing and spent the night in jail. Vitalii Sediuk, the same guy who got slapped in the face by Will Smith last year for attempting to kiss the actor, tells the Hollywood Reporter he walked into the Grammys with a friend who had a ticket and he was never asked by security to show his.  He said he found an empty seat behind Justin Timberlake and when Adele’s name was announced he decided to rush the podium. Sediuk tried to grab the mic from presenter Jennifer Lopez, who shooed him away, but not before he got out the words, “Thank you Adele. You are my inspiration.”   Sediuk told the Hollywood Reporter he didn’t mean any harm, explaining, “I’m not a crazy guy. I just think differently.”

He’s already been on the UK edition of the show, but could Ne-Yo be replacing Britney Spears orL.A. Reid as a judge on the U.S. version of The X Factor? During a red carpet interview at the Grammys on Sunday, he told Extra, “I think it would be a great, great thing. I don’t want to talk too much about it, because I don’t want to get in no trouble. Conversations have been had, but that’s about it.”

It appears Justin Timberlake and Jay-Z will continue their partnership on tour. According to the New York Post, the two superstars, who teamed on “Suit & Tie,” the first single off Timberlake’s forthcoming album The 20/20 Experience (due March 19), which they performed live at the Grammys, are planning to mount a 10-date stadium tour together. Rolling Stone cites sources who say the trek could climb to as many as 13 shows. Reportedly, Timberlake said on the red carpet at the Grammys, “We’re definitely going to go on tour… I don’t know how much I should say,” though he never specified who “we” was.
