Sienna Miller Denies Breaking Up Sean Penn, Robin Wright

Rumours are making rounds that actress Sienna Miller is the reason Robin Wright filed for divorce from her husband of 11 years, Sean Penn.

However, Miller's rep has insisted that the reports are "outrageously untrue.
Sienna is a very good friend of Robin. She adores and respects Robin.

"A source recalls that Miller was spotted cozying up to Penn at a New York hotel while Wright was home alone with the kids.

"Sienna was sitting on Sean's lap. She was dressed very sexily. She had her arm around his neck, the New York Daily News quoted the source, as saying.

Penn's friend maintains that there is nothing brewing between the two. Sienna is like that with everyone. She's very physical. She drapes herself over people she likes. She doesn't mean a lot by it, the pal said.
