Rachel McAdams and Jake Gyllenhaal share a dinner in Pittsburgh

Though they've been the subject of dating rumours in the past, costars Jake Gyllenhaal and Rachel McAdams shared a friendly meal this week.

The actors, who are currently in Pittsburgh filming Southpaw, stopped into comfort food-haven Meat and Potatoes for a casual bite on June 3.

The evening was captured by a patron, who later uploaded a photo to Instagram with the cheeky caption, “Why is my girlfriend Rachel McAdams eating dinner with Jake Gyllenhaal.”

Southpaw also stars Academy Award winners Lupita Nyong’o and Forest Whitaker. The story follows a boxer who is fighting his way to the top of the ranks, only to discover that life around him is falling to pieces.

In 2010, Eminem (also known as Marshall Mathers) was slated to play the lead role, but he halted production to focus on his new album and Dreamworks shelved the project. Since then, Sony Pictures Entertainment has greenlit the production, swapping the 8 Mile actor for the Donnie Darko star.

Eminem co-wrote the film’s screenplay with Sons of Anarchy creator Kurt Sutter.
