London, Oct 22 (ANI): Britney Spears has left fans open-mouthed after getting plastic surgery to pump up her lips.

The troubled singer went to a Beverly Hills plastic surgeon at the weekend and emerged from the clinic covering her mouth.

But it seems that the injections were a little too much, for they left Britney with a trout pout.

A LA source said that Britney ended up looking 'freaky' after getting her lips injected with collagen.

"Brit hoped her new lips would improve her look without being really obvious to anyone. But onlookers literally stood opened mouthed when they saw her. She looked freaky," the Daily Mail quoted the source, as saying.

Things are looking up for Britney though - she was allowed a visit from sons Sean Preston, two, and Jayden James, one.

On Thursday, Kevin Federline's lawyer, Mark Vincent Kaplan, said he expected Spears would get visitation reinstated soon because "she has complied with the part of the order [causing the suspension]." (ANI)
