London, Sept 2 (ANI): Actress Sienna Miller might have denied a number of times that she and Rhys Ifans aren't an item, but there's something definitely going on between the two.

The two were spotted cosying up at the bash for Miller and her sister Savannah for their new fashion range Twenty8Twelve.

A source said that Ifans made a mock proposal to Miller as he took of his shirt and kneeled down

"Rhys was kneeling, stripped to the waist, gazing up at Sienna who started shrieking with laughter. It was a bit of a sight, Rhys is the shade of milk and really puny - he looks better with his clothes on than off,' the Mirror quoted the source, as saying.

"And of course he was dripping in beer. After a while Sienna looked a bit embarrassed - especially as all her family were there," the source added.

Recently, Ifans was spotted leaving the 'Factory Girl' star's house, but Miller insisted that the actor was only crashing on her couch

"Rhys is crashing on my couch - we're not sleeping together," she said. (ANI)
