"It's pretty bad," she confessed of her reputation. "On the whole, you know, I've made some bad choices and done some stupid things."
So isn't it interesting that just this past Sunday (which also happened to be Father's Day), Sienna was spotting frolicking topless and smooching Balthazar Getty again in Italy?
She made headlines for doing the same thing last year when the father of four was still married to Rosetta Getty.
The two supposedly split in late 2008, but by the looks of last weekend, they're back on.
Balthazar's mother was also on hand for their weekend vacation in Positano, where they boating and swimming together.
No word on how his kids spent the day.
