You gotta hand it to Sienna Miller. That woman moves fast.

Just weeks after ending her 9-month relationship with Rhys Ifans (Notting Hill), the 26-year-old actress has reportedly moved on to her next target: a married Balthazar Getty. Getty, 33, was supposedly introduced to the blonde bombshell through his Brothers & Sisters co-star, Matthew Rhys - another rumored ex of Sienna’s.

According to the British tabloids, this upsetting news has driven Balthazar’s wife to seek a divorce lawyer. Rosetta Getty has also taken their four children, including an 8-month-old baby girl, to a family villa in Italy. Meanwhile, Sienna and her new beau have reportedly been spending time together in the Los Angeles area.

If the stories are true, this would make the second high-profile affair for Miller. Jude Law was a married father of three when he and his Alfie co-star became involved.
