Carrie Underwood + Travis Stork = Reality match

Tabloids have been dancing around the issue of a romance between onetime reality stars Carrie Underwood (American Idol) and Travis Stork (The Bachelor: Paris). From the looks of things Monday night at Parc on Rittenhouse Square (patting on back, toasts, hand-holding...), sparks are flying.

They just happened to end up in Philly together. Underwood, 25, performed Sunday at the Liacouras Center. Stork, 36, an ER doc, emerged from the Sofitel on Monday morning to do interviews in support of The Doctors, the medical talk show that airs weekdays at 3 p.m. on CBS3.

At Parc Monday night, a patron in a birthday party got a rise out of Underwood, who joined in singing "Happy Birthday."
