Sir Paul McCartney dating Christie Brinkley?

The pair are both currently holidaying in The Hamptons and ran into each other at a James Taylor concert.
Paul, 64, and Christie, 53, are said to have slow-danced and "cuddled" during the romantic song 'How Sweet It is To Be Loved By You', and spent most of the night together.
The former Beatle is currently going through a messy divorce with Heather Mills, while four-times married Christie is in the process of divorcing architect Peter Cook, who she wed in 1996 and split from in 2006.
However, Christie's second husband Billy Joel is doubtful the pair will become an item, and insists she knows the 'Yesterday' singer through him.
