During Wednesday's (30.06.21) episode of Bravo's 'The Real Housewives of Beverly Hills', the television personality revealed her and husband Harry Hamlin's 20-year-old daughter told her she was "just friends" with the 38-year-old socialite when they were first seen together on Halloween last year.

She continued: “And then, I guess a couple of days ago, Amelia sends me a video of Amelia and Scott on the beach."

Erika Jayne then asked: “So there’s something to it?”, to which she replied: “Yes.”

Lisa has made no secret that she is disapproving of the couple's 18-year age gap.

She admitted: “It’s a what the f*** moment. You’re like, ‘What the f***?’ She’s 19. He’s 37 with three kids.”

The 57-year-old author insisted her husband was “calm about it", however she was “a lot more nervous about it.”

And the former 'Melrose Place' star didn't know what to do and whether or not to talk to Kris Jenner - the grandmother of Scott and his ex-partner Kourtney Kardashian's kids Mason, 11, Penelope, eight, and six-year-old Reign - about the pair.

She continued: “We’re thinking it’s a phase, right? It’s a phase, I don’t want to bring attention to it.

“Should I text Kris [Jenner] and be like, ‘Welp …’ I’ve done nothing in other words because I also don’t want to bring any attention to it.”

Lisa also took issue with the fact Scott didn't marry the mother of his three kids.

She added: "And Scott was with Kourtney, not married, they have three children. Oh, God.

“As a mother, I’m like, ‘Good, this gives her another label to deal with.’”

It was previously claimed the age difference between Scott and Amelia doesn't matter to the couple.

A source said: “Despite their age difference, they have more in common than people would think. He sees himself as being younger than he is. Amelia is really mature and acts older than she is, so they get along pretty well.”
