Tallulah Willis’ sister Scout reacts to rare comments about ex-stepdad Ashton Kutcher

Two of Demi Moore's daughters have now spoken out about their former stepdad Ashton Kutcher, after one admitted the 'rare' comments should have 'been a private message'.

The star's youngest daughter Tallulah Willis accidentally spoke about how to navigate having an ex-step parent, in the comments section of an Instagram post shared by Gwyneth Paltrow.

Moore is mum to three daughters, Scout Willis, 33, Tallulah Willis, 31, and Rumer Willis, 36.

The 31-year-old is notoriously private about her personal life and that of her mum Demi, and rarely comments about her mum or her former stepdad Ashton.

But when Paltrow opened up on a recent podcast about the 'messy, beautiful, and often surprising realities of step-parenting', Tallulah spoke up about her own experiences, which she later admitted shouldn't have been a public admission.

She wrote: "I have a lot to say on this! Especially how to move through an ex-step parent."

When a commenter replied asking if this was about her former stepdad Ashton, she awkwardly responded: "This maybe should have been a private message lol but yes I have personal experience with this."

But her older sister Scout has now jumped in on the conversation, speaking about her sibling's blunder with Entertainment Tonight at the premiere for The Carters.

When a reporter asked about Tallulah's slip-up, she said: "Well, Tallulah is not nothing if not vulnerable and wonderful online."

But she also had a lot to say about her experience of having a famous mum and step-dad.

Agreeing with her sister, she said: "I think, since my parents divorced when I was young, it’s always been handled with absolute grace and love, and I think that really is the way forward for everything.

"It’s just like putting the children first and just handling everything with a lot of mutual respect."

Their parents are Demi Moore and Bruce Willis, but Demi remarried Ashton in 2005 when Tallulah was just 11 years old. They went on to split in 2011 and divorce in 2013.

Ashton was part of Tallulah's life throughout her teenage years, as she later added: "It's an important conversation to be honest.

"Also no one needs to be bad guy for a situation to be healed. There's room for everyone."

She previously opened up about the relationship between Demi and Ashton on an episode of Stars On Mars, saying she didn't realise how famous her parents were when she was growing up.

"I knew my parents had this job that made them like this thing and we got to do cool stuff, but I didn't fully understand," she confessed.

“It was like, 2003, my mom had just started dating Ashton, it was that moment," Tallulah revealed.
