Robbie Williams

Has Robbie Williams paid a visit to the Playboy Mansion?

Why else would he be in his pyjamas surrounded by ladies?

Well this time, Rob's tomfoolery is of his own making. 

The singer hosted a party with what seems to be a large group of pj-clad ladies - in honour of the Christmas season.

As you do.

We're not quite sure what the flannels represent in terms of the festive spirit, but we're loving the pic anyway.

And not to mention that Robbie is adorable in his tartan togs.

He looks very happy indeed as he poses with a gaggle of girls - who in turn look extremely excited to be snapped with the lothario.

The party was held at Rob's LA pad, so we wonder whether he stripped off to something a little smaller later in the evening? We all know that he's partial to a bit of a flesh-flash.

Then he'd definitely be giving Mr Hugh Hefner and his bunnies a run for their money.
