Rehab star Amy is all smiles after getting her teeth fixed ahead of Grammy performance tonight

Amy Winehouse is all smiles these days – after finally being granted a US visa and getting her teeth fixed.

Despite the star's changing luck, she will not be performing live at tonight's celebrations.

Instead, the 24-year-old, whose album Back to Black has been nominated for Grammys in six categories, will sing via a satellite link from London.

She had previously been denied entry to the US but will be staying in the UK to focus on her recovery as she is weaned off drugs – and her sparkly new teeth.

Emerging from a second visit to a London dentist yesterday, Amy flashed a bright white smile to onlookers before being escorted by her father Mitch back to the centre she is receiving treatment in.

This is a far-cry from December when she was spotted with gaps in her mouth suggesting her teeth had fallen out.

A friend close to her admitted at the time: "She has one missing from the front of her mouth, and another one at the back which is less visible.

"Her mouth is full of holes and she is desperately worried she is going to lose more. She has actually pulled a tooth out herself, which is absolutely disgusting."

"Her gums are always red and sore as a result of it and some of the teeth are loosening."

Rehab appears to be agreeing with Amy in more ways than one.

The singer seemed focused, was well-dressed and had even painted her nails red for the occasion.

Is This The New Britney Spears Blender Cover?

Let us preface this post by saying we don’t know for sure if this is the real Britney Spears Blender cover or not. It could be completely fabricated and fraudulent. But real or fake, its fun.

That being said, if this is real its brilliant. We love the cigarette butts in the Mickey Mouse ears and the red bull can. And the tag line for her story is fantastic. Its so perfect it makes us think its fake. This picture is obviously Britney’s head shopped onto to some other hot body, but if you all remember a few months ago there was a rumor that Blender was holding an open audition for a Britney body double.

What do you think? Fake or real?
