Sienna MillerSienna MillerThere's been a lot of speculation over Sienna Miller's love life recently, and whether or not she plans to reunite with Jude Law.

So it's no surprise that her every move seems to attract attention.

This time, she's raised eyebrows by having a night on the town with actor Daniel Craig - her co-star in the Brit hit Layer Cake.

Daniel - who's been tipped to be the next James Bond - has been romantically linked to the likes of supermodel Kate Moss in the past.

He kicked off the evening by watching Sienna in As You Like It at London's Wyndham Theatre.

"Daniel sat down next to Sienna's mother in the audience, but had to move when the people who had those tickets arrived," a source told the Daily Mail.

They went to the swish Ivy restaurant for dinner - and the pair eventually left separately at 1am.

However, The Sun reports that they met up again at a party at London's Cafe Royal, and stayed until the early hours.

And ever the gentleman, Daniel chauffered Sienna home at 7am.
