New York, Oct 2 R 'n' B singer Mariah Carey is said to have turned up at a restaurant looking a little wobbly on her feet.

According to a witness, Carey, 39, arrived at One Little West 12th at 1:30 a.m. with her brother and a few bodyguards and was quite out of it.

When she exited her black Maybach, she tripped twice and had to grab hold of one of her guards so she wouldn't fall, and after she ordered a bottle of champagne but she could barely speak.

"She was probably wobbly because she was wearing 7-inch Louboutins. She had just completed 18 hours of press. That's tough to do," the New York Post quoted a source close to the singer as explaining her wobbliness. (ANI)
