Mark Ruffalo stopped by the show with Keira Knightley to promote their new movie Begin Again, but it was a different female costar that fans were curious about.
The 46-year-old actor was asked by a viewer if he still kept in touch with 13 Going on 30 pal Jennifer Garner, and Ruffalo had a surprising answer.
"We have a great time together," he said of filming the movie. "But then Ben came on the scene."
Thinking Ruffalo's remark about Garner's hubby, Ben Affleck, was a comedic quip, host Andy Cohen responded, "I heard he doesn't allow her to have male friends?"
Instead of laughing it off, Ruffalo just shrugged, and said he couldn't confirm or deny the statement.
He and Garner played love interests in the 2004 rom-com, which came out around the same time that the Alias star and Affleck started dating.
