Sarah Michelle Gellar and Jerry O’Connell go way back.

Gellar appeared on Thursday’s “The Talk”, with Amanda Kloots mentioning how the pair — O’Connell is now a “Talk” co-host — used to date at one time after attending the same high school.

Gellar told the panel: “I think you’re getting the more subdued, calmed-down Jerry, actually. You’re getting the more mature, fatherly Jerry, the lessons-learned Jerry. I had the actual energetic Jerry.

“I should also tell you that the high school part has all gotten confused because I was a freshman and he was a senior. He never acknowledged me. It was only later that you would actually talk to me.”

O’Connell insisted, “Listen, I was a senior. I didn’t want to come off as too much of a predator. I respected age differences and everything. By the way, this is not a filter. You have never seen me blush as much as I have on this show.

“You look beautiful. I’m so happy for you. I follow you on social media.”

They didn’t confirm when exactly they dated, but the pair did attend the 1998 Emmy Awards together when she was a 21-year-old “Buffy the Vampire Slayer” star and he was 24 and starring in the series “Sliders”.
