Paul McCartney, just weeks after being linked to NYC millionaire businesswoman Nancy Shevell, is now rumored to be dating actress Rosanna Arquette. The pair were first linked earlier this year, and have now been spotted enjoying two dates together in less than 24 hours.

Last weekend, Paul reportedly fetched Rosanna from a friend's home in West London, and then drove her back to his house in St. John's Wood. They spent two hours in the house together, before departing once again. Rosanna slyly ducked down in the back seat of the car, and was then transferred to a waiting black cab.

It was all on the sly, but according to an onlooker, "Paul couldn't resist a quick cuddle. Rosanna was beaming after that."

The following day, Paul and Rosanna were spotted together again at Kenwood House in Hampstead. They wandered the grounds for about 40 minutes, before embarking on a tour of the house itself. Witnesses to the second sighting said, “They acted like teenagers on a first date. The body language said it all - they were almost joined at the hip. Paul looked very flirty. They had a couple of cuddles and a kiss. The sparks were there for everyone to see.”

It seems the former Beatle has become quite the ladies man again following his split from Heather Mills. In the past year, McCartney has been linked to a string of women, including Renee Zellweger, Sabrina Guinness, and Christie Brinkley.
