Paul McCartney has sparked engagement rumors after he was spotted shopping at a top London jeweler. The former Beatle was snapped by photographers shopping at exclusive New Bond Street store S.J. Phillips yesterday - fueling speculation he is to propose to American heiress Nancy Shevell.

The 65-year-old recently returned from a romantic Caribbean vacation with Shevell after settling his $48.6 million divorce from estranged wife Heather Mills last month. The pair was spotted getting close on the beach of a private resort - splashing out on a $12,000 -a-night villa, enjoying hand-in-hand walks along the coast, a sailing trip and frolics in the sea.

And now, the Mull of Kintyre hit-maker seems to have taken the relationship to another level with his jewelry store jaunt. S.J. Phillips confirmed McCartney was shopping at the store - but refused to say what the singer purchased during his visit.
