Drew Barrymore recalled once greeting Hugh Grant by kissing him for 10 minutes straight

• Hugh Grant and Drew Barrymore starred in "Music and Lyrics" together in 2007.
• On "The Drew Barrymore Show," the actress recalled greeting Grant by kissing him for 10 minutes.
• Grant called the incident "bizarre" and said the producers with him didn't know what to think.

Drew Barrymore and Hugh Grant caught up with each other on Barrymore's chat show, and recalled a "bizarre" story in which the actress said hello to Grant by making out with him for 10 minutes straight at a restaurant.

Grant, who costarred with Barrymore in 2007's "Music and Lyrics," appeared on "The Drew Barrymore Show" on Thursday, May 20 when the story came up.

"I walked into, I think it was like the Waverly Inn. This was years ago - and 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," Barrymore recalled.

Grant responded: "Yes, I remember that."

Barrymore went on to act out how Grant reacted to the kiss, describing Grant's expression as "'you've never greeted me that way before.' And then you had a second thought, and you were like, 'You know, I'm not hating this.'"

Barrymore recalled that the two of them flirted and then promptly said their goodbyes to one another.

"It was really bizarre," Grant said. "I was very drunk as well, and I was with some very nice but not drunk studio executives from L.A., and they were very surprised."

"Someone said, 'Oh, there's Drew Barrymore.' I get up to say hi, and then we make out for 10 minutes, and then I sit down again, and we go and talk about the script," Grant said.

Barrymore suggested that the two of them had grown up since then, with Grant replying that he hates responsibility.

Part of those responsibilities for "Bridget Jones' Diary" star Grant include raising five children, three of which are with his wife Anna Eberstein, who he married in 2018.

Meanwhile, Barrymore, who has been divorced three times, has two children. She had both of her daughters with her ex-husband Will Kopelman. Barrymore has been single for five years but recently said that "Bridgerton" inspired her to reactivate her profile on a dating app.

Grant spoke about several of his leading lady costars while appearing on "The Graham Norton Show" in 2016. Norton read out a list of comments Grant had previously made in 2009 to Elle Magazine about his former costars, which included Barrymore. About Barrymore, Grant said: "Made her cry, hates me."

Grant told Norton: "She made the mistake of giving me notes."

It seems Grant and Barrymore are good friends now, though.

Grant most recently starred in "The Undoing," an HBO murder-mystery series with Nicole Kidman that received lukewarm reviews for its controversial ending.

Meanwhile, in a recent interview with Dylan Farrow, Barrymore explained that she felt "gaslit" by Woody Allen when she worked with him on the 1996 movie "Everyone Says I Love You."
