Sienna Miller, who has gone through her fair share of leading men in her time, seems to be moving to the comedy side after being seen out with County Down comedian Patrick Kielty.

The two were spotted leaving a party together in London a few weeks ago and seemed to be getting on very well.

For Miller, the star of "Alfie," "Factory Girl" and the soon to be released "Hippie Hippie Shake" with Cillian Murphy, dating someone who is not an actor is a depart from her norm.

A few years back, the English blond was very much with English heartthrob Jude law until he decided to jump his nanny, and since then the 27-year-old has been linked with Welsh actor Rhys Ifans and more recently Balthazar Getty.

Kielty is a native of Dundrum in County Down and has enjoyed a strong career in Britain.  The 38-year-old had to deal with tragedy early in his life when his father was murdered by the Ulster Freedom Fighters.

Though Kielty featured political comedy in his routines early in his career when he was a student at Queens University, he has concentrated on mainstream subjects as his popularity has grown.

It is not the first time Kielty has dated someone in the public eye.  The comedian had a relationship with Irish TV personality and former model Amanda Byram for several years.

If he is bringing a smile to Miller's eye now, then more power to him!
