Britney Spears isn't shying away from sexually suggestive lyrics after the fuss over If U Seek Amy (sounds a tiny bit like F*CK Me if you say it quicky).

The title of her new dance track – 3 – refers to some naughty three-in-a-bed action.

With autotune cranked up to 11, she 'sings': "1, 2, 3/Not only you and me/Got 180 degrees and I'm caught in between.

"What we do is innocent/Just for fun and nothing meant/If you don't like the company/Let's just do it you and me."

Brit's ode to threesomes is taken from her upcoming greatest hits album. Listen to the full track below.
