Sienna Miller now regrets chasing Balthazar Getty

After a recent reunion with old-flame, Balthazar Getty brought her yards of bad press, Sienna Miller has now admitted she made a bad choice.

The 27-year old Brit, who can be seen in the upcoming swirling vortex of suck more kindly referred as  ‘G.I. Joe,’ now tells reporters she’s aware her affair with the married actor may have upset her fans, “It probably looked awful,” she says calmly, displaying that effortless gift of the Brits for vast understatement. “I probably seemed not a particularly nice person. Not a girl’s girl,” she told Us Magazine.

But despite being singled-out by the press, and most of her fans as the primary reason why the young Getty’s nine-year marriage to fashion designer Rosetta Millington – with whom he has four young children – is now on the rocks, Sienna is utterly unfazed by the blame;  “I’ve always done what my instincts said. I have a good brain… but I’ve never used it when making decisions about love,” she explains. “But I definitely have been quite foolish.”

Some tabloid reports on the affair suggested that Sienna had a sexually manipulative nature, which the actress denies. “I’m supposed to be this complete slapper; That’s my reputation,” she admits. “But actually I was in three relationships from age 19 to 26. Then a few dalliances – three months here and there. But I’ve been single for the past year and it’s been really great.”

Sienna  was then asked if she felt her ill-fated liaison with a rich, married man had changed her at all? “The situation I got into was not ideal, but if I could go back again, I would,” she replied. “I think I’ve grown up a lot.”
