Lisa Rinna has hit out at the age difference in her daughter's relationship with Scott Disick. Amelia Hanlin,19, has officially been dating Kourtney Kardashian’s 37-year-old ex since February, and her mum doesn't like the huge age gap. He has three children with the eldest Kardashian sister; Mason, 11, Penelope, eight, and six-year-old Reign.

A scene from the teaser for season 11 of Real Housewives of Beverly Hills shows Lisa, 57, Face Timing with her daughter.

"He's too damn old... and he's got three kids!" shouts pal Kyle Richards, before Lisa agrees and chimes up saying: "I know!" It's one of the only comments in public from Lisa about her daughter's latest partner.

Lisa had previously shared a cheeky joke on social media and drew similarities between her and Scott's love of bucket hats.

"Welp we both seem to share a love of bucket hats," she joked, in reference to Scott modelling a hat from his Talentless collection.

Lisa then unveiled a picture of herself wearing a similar-looking black bucket hat, alongside a laughing face emoji.

Scott and model Amelia actually met as Lisa is friends with the Kardashian-Jenner "Momager" Kris Jenner.

The pair's relationship is seemingly going from strength to strength and there had been reports that they were thinking about moving in together in Miami, Florida. And it appears as though the relationship even has the blessing of Kourtney too.

Kourtney's close friendship with Scott was blamed for the breakdown of his previous relationship with Sofia Richie.

The daughter of singer Lionel Richie was said to have given Scott an ultimatum about seeing Kourtney, leading to the couple going their separate ways.

However, according to a source close to Amelia, Kourtney "doesn't bother her".
