Sienna Miller back with ex-beau?

British actress Sienna Miller who split with her actor boyfriend Balthazar Getty early this month has been spotted out on a date with him, sparking rumours that their romance is back on the track.

The pair went to San Lorenzo Italian restaurant in Knightsbridge, London, Thursday for lunch, according to reports.

The couple broke up due to Getty's stalling over his divorce proceedings with ex-wife Rosetta Millington that angered Miller, while her constant partying habits were not liked by the actor.
