Taylor Lautner and his "Tracers" co-star Marie Avgeropoules went on a romantic stroll in New York City on Saturday, according to Hollywood Life. 

The "Twilight" actor, 21, and the Canandian actress, 27, already look like lovebirds in the new PDA-filled picture, where they are holding hands. The twosome have been spending a lot to time on-and-off set before making their relationship official on July 29, reported HL.

The new couple took some selfies to let the world in on their new romance, looking so lost in each other. It looks like the pair are in their honeymoon phase, and that their on-screen chemistry has crossed over into real life, said several reports. 

Romance rumors began flying that the cute twosome were more than friends after cameras caught them at a Fourth of July party in New York City, HL reported.

A source said that Lautner likes Avgeropoules a lot, "She's totally his type and he's really excited about her." 

However, just as quickly as things are heating up, they might cool down even quicker, the source told the celebrity news site.

The co-stars might not be sticking together for the long haul, "Taylor's having a great time with Marie," the source said.

"But I doubt it will last after they finish the movie," the source continued. "My guess is that this will be a fun summer fling for Taylor because his number one priority is his career. He is extremely driven and ambitious and wants to become the biggest action star in the world."
