The former lovebirds, who broke up in December, were seen in deep conversation at an event
“They were outside near the restroom having a discussion,” a guest at the Vanity Fair bash tells PEOPLE. “It seemed a bit more serious – it certainly wasn’t a ‘Hi, how are you?’ talk.”
On Sunday night, Gyllenhaal and Swift were back together for a short visit at the party, and while there was no overt affection between the two. “It seemed like they were catching up,” says the source, “sorting something out.”
Soon after their chat, Gyllenhaal headed out while Swift stayed and partied with two girlfriends. “They completely kept to themselves,” says the guest. “She couldn’t be bothered by anyone.”
