Alicia Silverstone's seven-year-old son kept trying to smooch her after he watched 'Clueless'

But the youngster paid more attention to the finer details than Alicia had anticipated as he left the screening and tried to slip his tongue into her mouth after watching her lock lips on screen.

Speaking on 'The Late Show with Stephen Colbert' on Monday (11.06.18), she said with a giggle: "I took him to see it because it's at the L.A. Cemetery where they show it for 4,000 people.

"There were 4,000 people and this huge screen outdoors at night, in a cemetery, very romantic, and there were pillows and rosé.

"The one thing he took away from it, aside from all the things I was worried about, was he kept trying to French kiss me afterwards, which was very sweet."

Stephen - looking very concerned - asked: "And you said: 'That is not appropriate?' "

But Alicia could see the funny side to her son's experimental kiss and replied: "I just kept my mouth closed! That's what I did. And I just giggled. It's super sweet."

Stephen said hesitantly: "It is super sweet."

After a brief moment's silence, Alicia queried: "Yeah, are you worried?"

Stephen shot back: "Nope."

Realising how her description had come across, she explained: "It's fine, he's not doing it anymore. That's what his takeaway was."
