Dizzee Rascal claims writing 'Arse Like That' was a ''no-brainer''.

The rapper didn't have to think too hard about what subject to tackle when he heard the beat which backs his homage to the female posterior, as inspiration was close at hand.

He told BANG Showbiz: ''Basically I was working with Teddy Sky, who is a writer for RedOne and he had a bunch of tracks, and that one came on, and it was a no brainer. His screensaver on his computer was a bunch of fine arses from around the world! It was pretty easy to be fair!''

Dizzee doesn't mind if people compare his track to rap's most famous ode to butts - Sir Mix-A-Lot's 1992 classic 'Baby Got Back' - but feels his song is a fresh take on the subject.

When asked if how he'd respond to comparisons with 'Baby Got Back', Dizzee replied: ''Come on man, that's a classic benchmark, landmark, but if you go on [the internet] and type 'arse songs', there's a million of them.

''That's a classic though, and I'll pay homage, but I didn't even understand about anything like that when that [record was released]. It's my time now. It's gone down really well at the shows as well.''

'Arse Like That' is included on Dizzee's new album, 'The Fifth', which is out now.
