As Us Weekly was the first to report, Paltrow, 38, hosted a private dinner party for the pair during Swift and Gyllenhaal's secret trip to London on Nov. 13.
"Jake and Taylor were driven from the Dorchester hotel to Gwyneth and Chris Martin's house in Primrose Hill for dinner," an insider told Us. "Gwyneth seems to have played a role in their relationship."
When USA Today asked Paltrow about the intimate gathering with Gyllenhaal, 30, and Swift, 21, the "Country Strong" actress initially tried to play coy.
"Where is this coming from?" she asked, adding that she's "scared to say" much about the couple's blossoming romance.
"It's so weird. I wonder how people find out these things. It was a while ago, so I don't know why it would come out today," Paltrow said. "I've just known Jake for a long time and he's a great guy, and Chris has a friendship with Taylor."
Paltrow's matchmaking skills apparently paid off: one week after their trip, Swift scheduled a last-minute trip to Brooklyn to spend Thanksgiving with Gyllenhaal at his sister Maggie's home.
"They were so happy and content," an eyewitness told Us of the couple. "They seemed very comfortable together."
