R&B superstar Usher was left red-faced during a star-studded gala for former President Bill Clinton on Saturday night (15Oct11) when his trousers split midway through his energetic stage routine.
Lady Gaga, Kenny Chesney and U2's Bono and The Edge turned out in force to celebrate Clinton's belated 65th birthday and the 10th anniversary of his Clinton Foundation.
Usher was one of the performers at the A Decade of Difference event at the Hollywood Bowl - but suffered an embarrassing wardrobe malfunction when his pants tore on his left thigh as he belted out his hits.
Ever the professional, Usher refused to let the incident interrupt his three-song set and held on to his trouser leg during certain parts of his dance as he completed his performance.
Comedienne Ellen DeGeneres poked fun at the incident later on in the evening when she told the crowd as she walked on stage, "Sorry I'm late, I had a rip in my pants and I had to fix it."
Ashton Kutcher was also on hand to pay tribute to Clinton for his Foundation's work in alleviating poverty, improving global health and protecting the environment, while Bono and The Edge sang Happy Birthday to the former leader.
Gaga also marked Clinton's birthday by sending out a special message to him as she performed a saucy routine for the crowd, saying, "If someone had told me years ago that I'd be doing that in front of you, I wouldn't have believed them. I would have given them a good old American f**k you."
Clinton actually turned 65 on 19 August (11).
