Lisa Rinnahas been the subject of her fair share of headlines over the years.

And theReal Housewives of Beverly Hillsstar, 58, has been sure to impart some of the wisdom she’s collected along the way on her daughters,Amelia GrayandDelilah Belle Hamlin, who recentlyshared some of their mom’s best adviceon being in the spotlight. “She’ll be like, ‘Just F the haters,'” the sisters told ET.

“It’s kinda just part of it,” said Amelia, 20, whose romance withScott Disick, 38, has seen her receive a lot of attention. “You can’t even really say anything about it.”

“She just has always been like, ‘Oh, just ignore it!'” added Delilah, 23, who’s in a public relationship of her own withLove IslandstarEyal Booker, 25.

Amelia’s relationship with Disick recently received some extra attention, as Rinna, 58,reacted to news of her daughter’s love lifeon an episode ofRHOBH. She called the pairing a “what-the-f— moment,” adding that she’s “a lot nervous” about the situation. “She’s 19, he’s 37 with three kids. Hello!” Rinna said.

“Amelia has had her struggles in the press, but it’s now a new headline,” Rinna said in a confessional. “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.”

Rinna’s husbandHarry Hamlinalsochimed in on the relationship, comparing it to his former relationship withUrsula Andress, who’s 14 years his senior. Harry, 69, and Andress, 85, were briefly engaged after meeting on the set of the 1981 movieClash of the Titans, and they share son Dimitri Alexander, 41.

“My feelings about it, I must confess: the issue that’s the most enduring is the age difference, which to me is odd,” Harry confessed in the latest episode. “But, then again, every time I think of that, I think of myself and Ursula Andress. I was 14 years younger than she when we had [our son] Dimitri, so I can’t really complain, right?”

Amelia and Disick were first linked in October, and theymade their relationship Instagram officialduring Valentine’s Day weekend. A source later told PEOPLE in March that Disick"is getting serious"with the model. “It’s a different type of maturity, and they really don’t feel the age difference,” the insider added.

Disick shares sons Mason Dash, 11, Reign Aston, 6, and daughter Penelope Scotland, 9, withKourtney Kardashian, 42, whom he dated on-and-off from 2005 to 2015.
