Melbourne, Nov 23 American actress Meg Ryan has sparked specuation she's dating Nip/Tuck star Julian McMahon after photos of them emerged in Woman's Day.

Ryan, 48, and McMahon, 41, have been linked following a series of "cosy" dinner dates in LA, with one date said to have gone on for four hours with them doing some hand holding, reports News.com.au.

While Ryan is single, two-time divorcee McMahon has a steady girlfriend, the gorgeous Kelly Paniagua, who often travels Down Under with him, most recently in August.
