Sienna Miller And Balthazar Getty Together Again?

After reportedly calling a day on their controversial romance earlier this month, it seems that Sienna Miller and married lover Balthazar Getty have been unable to go their separate ways.

The pair had lunch and then spent an evening at London's Groucho nightclub, but made sure they weren't photographed together by leaving separately.

The Alfie actress - who has been romantically linked to Josh Hartnett in recent weeks - was said to have looked smitten with her ex yesterday morning.

"'They looked so much in love,"  an onlooker told The Sun.

"Sienna was clutching Balthazar's hand and giggling as they strolled along together."

Sienna and Balthazar became the most reviled celebrity pairing in recent years after flaunting their affair with a very public yacht-based display of affection.
