WASHINGTON - It seems Heather Mills has finally moved on after her split with Paul McCartney, as she was recently spotted with a guy who is a rookie driver in the ARCA stock car series.

The former model came to Mercedes-Benz Polo Challenge at Blue Star Jets Field in New York’s Hamptons, where she evidently loved talking to Tim George, Jr.

“Now that Paul has moved on with his girlfriend, Nancy Shevell, Heather thinks it’s about time she moves on, too,” a source told FOX411.

The insider added: “She was so into Tim, chatting with him, smiling ear to ear and hanging on his every word. They posed for photos together and kind of watched the match, but they were busy talking up a storm.”

The two reportedly met once again the same night at Social Life Magazine party for the mag’s August issue, which features Tim on the cover.

The source briefed: “Heather was definitely into Tim, and it seemed he was into her, too, from how easily their conversation seemed to flow. They were inseparable!” (ANI)
