Could Jake Gyllenhaal and Rachel McAdams be dating? Well their latest outing is doing little to dispel romance rumors.

According to E! News, the 33-year-old actor and Ryan Gosling's 35-year-old ex-girlfriend are currently staying in Pittsburgh to film their new movie "Southpaw." Earlier this week the pair took a break from the movie set and went out for a quaint dinner.

The costars headed over to Pittsburgh's Meat and Potatoes restaurant for a bite to eat. Jake Gyllenhaal kept his look casual wearing black track pants and a white jersey while Rachel McAdams covered up in a dark green jacket.

A source from the restaurant revealed that the two "loved everything" they ate during the meal. "They actually finished everything!"

Although the attractive pair had a nice dinner date together, a source told the celebrity news site that there is nothing romantic going on between Gyllenhaal and McAdams. They actors are strictly friends and costars.

However, that didn't stop a fan from snapping a secret photo of the two at dinner and posting it to Instagram. The admirer from afar attached the caption, "Why is my girlfriend Rachel McAdams eating dinner with Jake Gyllenhaal."

"Southpaw" tells the story of a boxer played by Jake Gyllenhaal who's fighting his way to the top of his sport only to find his personal life falling apart in the process.
