Taylor Lautner and Marie Avgeropoulos have finally confirmed that they're dating.

The relationship news comes just days after the Tracers co-stars were spotted walking around the SoHo neighborhood displaying their off-screen romance.

The 21-year-old Twilight star wore a La Mer graphic t-shirt, jeans, a Yankees cap and Adidas sneakers, while the 27-year-old brunette opted for a Batman-embellished top, short shorts and black sandals. The actress is also shown without her cast, after suffering a leg injury, and instead, had on a small black leg wrap.

The couple then were seen taking a picture with one of their iPhones. Lautner did not smile, but Avgeropoulos flashed her pearly whites.

Prior to making their relationship public, the two were spotted filming in tight quarters in NY on Saturday. The actress seemed to be holding onto him from the back and Lautner leaned in and whispered into her ear, as pictures show on MailOnline. 

In addition to hanging out on set, the couple attended a Blue Man Group performance on July 15. There have also been rumors that they were together on the Fourth of July.

Friends are skeptical about how long this summer romance will last though.

"Taylor's having a great time with Marie, but I doubt it will last after they finish this movie," a source told HollywoodLife. "My guess is 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."

Tracers is about a NYC bike messenger (Lautner) who escapes into the world of parkour after being followed by the mafia. The messenger meets a beautiful stranger (Avgeropoulos) along the way and more drama erupts. The movie hits theaters next year.
