Hot couple: Taylor Lautner and his co-star

Is a new on-set romance blossoming before our very eyes?

Twilight alum Taylor Lautner, 21, and his Tracers co-star Marie Avgeropoulos, 27, have been spotted getting cozy around New York City lately while filming their new flick.

In the movie, Lautner plays a bicycle messenger wanted by the Mafia.

On Monday, the two were spotted holding hands in Soho. And taking a selfie. Didn't seem to be part of the script.

While Lautner's Twilight co-stars Kristen Stewart and Robert Pattinson have been in the romance spotlight a lot, Lautner's love life hasn't been as splashy. Past loves are said to have included Selena Gomez, Lily Collins, actress Maika Monroe and Los Angeles Clippers cheerleader Sarah Hicks.
