Amy Winehouse keeps it all covered up under a shirt as she goes for dinner in London

Amy Winehouse these days, her outfits always seems to be struggling to contain her assets.

But last night, her headline grabbing surgically enhanced breasts were kept firmly under wraps.

In London the singer was snapped out for dinner and looked very reserved in a blue checked shirt and v-necked jumper.

She left seafood restaurant Fishworks with a couple of friends in tow before stopping at bar Balans for a drink on the way home.

And considering her eye popping attire of late, it made a nice change to look the 26 year old songstress covered up.

However, in London the weather has been miserable over the past couple of weeks so maybe she was starting to feel the chill as autumn approaches.

In current weeks, Amy - who had cosmetic surgery on her breasts to double her cup size last October - has been seen out and about at events in very very low cut dresses that have left little to the imagination.

She had trouble containing them in a tiny black dress as she and boyfriend Reg Traviss attend the press launch of Shaka Zulu, at Stables Market in Camden, earlier this month.

She even made sure her £35,000 breasts were showing last week when she visited her father Mitch in hospital after he was taken to a Harley Street clinic after he was diagnosed with gallstones.

But last night she kept her assets away from the flashbulbs in London as she enjoyed a quiet night out and was driven home early.
