Once upon a time, during a drunken night out, Drew Barrymore and Hugh Grant admitted to having a steamy makeout session. But what’s funny is they never discussed it until years later.

“I don’t think we’ve ever talked about this,” Barrymore recalled in an episode of “The Drew Barrymore Show,” for which Grant was the special guest. “I’d had a few drinks, and I walked in, and I ran into you, and instead of saying hello, I grabbed you by the collar, and I fully started kissing you.” Grant confessed that he indeed remembered the incident, telling his former co-star that she had “never greeted me that way before.” He said that at the time, he thought that “I’m not hating this,” so he just let it happen. Barrymore added, “And then we flirted, and then we were like, ‘OK, yeah, bye! See you soon.'”

Grant went on to acknowledge that it was “really bizarre.” He initially thought that he would just be saying hi to Barrymore, but then “we make out for 10 minutes, and then I sit down again, and [he and studio executives] go and talk about the script.”

And while they both admit that it was awkward, it helped them be comfortable with each other on-screen. In 2007, when MovieWeb asked if they had any bad moments on-set where they grew sick of each other, Barrymore simply said, “There is no bad for me.”
