'RHOBH' star Lisa Rinna reacts to her daughter Amelia Hamlin's relationship with Scott Disick: 'She's 19! He's 37 with 3 kids'

• Lisa Rinna weighed in on her daughter Amelia Hamlin's relationship with Scott Disick on "RHOBH."
• She said learning about the romance was a "what the f--- moment" and admitted to feeling "nervous."
• On Wednesday's episode, Rinna said: "She's 19, he's 37 with three kids. Hello!"

Lisa Rinna, a reality star on Bravo TV's "The Real Housewives of Beverly Hills," admitted she wasn't thrilled to learn that her daughter Amelia Hamlin, 20, is dating Scott Disick, 38.

On Wednesday's episode of "RHOBH," Rinna addressed the romance during a conversation with her costar Erika Girardi, explaining that Hamlin initially told her she was "just friends" with the "Keeping Up With the Kardashians" personality. Hamlin was 19 years old when she was first linked to Disick, then 37, in October 2020.

When Rinna got confirmation that Hamlin and Disick were in a romantic relationship, she said it was a "what the f--- moment."

"She's 19, he's 37 with three kids. Hello!" she said.

Rinna continued to tell Girardi that her daughter's relationship makes her "nervous." Her husband Harry Hamlin, however, was "more calm" when he heard the news, likely because the "Clash of the Titans" actor dated actress Ursula Andress when he was 28 and she was 44, Rinna said.

Though sources have claimed the couple is getting more serious with time, Rinna said she views the relationship as a "phase" for both parties and she doesn't "want to bring any attention to it."

"Amelia has had her struggles in the press but now it's a new headline," she said during a confessional.

Rinna continued: "No one's talking about the eating disorder anymore. And you know what, thank God. As a mother, I'm like, 'Good.' This gives her another label to deal with."

Prior to dating Hamlin, Disick spent nearly 10 years in an on-again, off-again relationship with Kourtney Kardashian. They had three children together - Mason, 11, Penelope, 8, and Reign, 6 - before officially parting ways in 2015.

The "Flip It Like Disick" reality star then had a three-year romance with Sofia Richie, who is 16 years his junior. They broke up in August 2020.

Because Disick has been much older than his two most recent long-term partners, some people have accused him of intentionally seeking out younger women. This narrative, he said, is false.

"Everybody gets this wrong, that I look for young girls," he said during a reunion special for "Keeping Up With the Kardashians" in June.

Disick continued: "I don't go out looking for young girls. They happen to be attracted to me. Because I look young."
