Renee Zellweger

A source said: "Renée smiled and laughed and hung on McCartney's very word.
She has a history of dating musicians and he's a legend, and single.
"He is also known to have a thing for younger women - and blondes."
Renée divorced singer Kenny Chesney in 2005 after just four months of marriage, and previously had a two-year relationship with the White Stripes rocker Jack White.
Paul is currently divorcing estranged wife Heather Mills, but has recently been linked to 53-year-old ex-model Christie Brinkley.
Brinkley was also present at the New York concert and was said to be seething over the level of attention Paul paid Renée.
But a friend of the 'Get Back' rocker claimed the pair were just enjoying an innocent chat and insisted: "Nothing's going on. Paul just got chatting to Renée."
An insider added: "I don't believe there's anything between them.
"Paul was sitting with US comedienne Amy Poehler and her husband, and Renée was with two friends and left 15 minutes after he did."
