We’re thinking this could get a little awkward at times.

Patrick Schwarzenegger — who’s rumored to be dating country-pop superstar Taylor Swift — is currently filming his big-screen debut, Grown Ups 2.

His co-star?

None other than Taylor Lautner, who famously dated Swift beginning in 2009.

Schwarzenegger and Lautner were spotted filming scenes for the Adam Sandler movie in Massachussets on July 8. The flick, which is a sequel to 2010’s Grown Ups, also stars Salma Hayek, Chris Rock and Andy Samberg.

Rumors of a Schwarzenegger/Swift romance began swirling last week when the two spent the Fourth of July together on the Kennedy family’s famous property in Hyannis Port, Mass. The 22-year-old singer was spotted walking on the beach with Schwarzenegger, 18.

The young man certainly enjoyed his Independence Day with Swift. He later tweeted: “Had such an amazing day. Best 4th of July I could ask for. Hope everyone had a great day!”

Swift and Lautner, meanwhile, dated in 2009 after meeting on the set of Valentine’s Day. Swift reportedly chronicled their relationship — and its demise — in her song, “Back to December.”
