In an interview with Howard Stern on Sirius XM, Rumer Willis has opened up about her mother Demi Moore’s marriage to Ashton Kutcher.

Rumer Willis, 26, admits Ashton Kutcher and Demi Moore’s May-December romance was awkward given that Kutcher was one of her celeb crushes when she was younger.

“He was one of many on the wall, but I totally did,” Rumer Willis said about hanging Ashton Kutcher’s poster in her bedroom.

“I feel like I told my sister that, <<Man, ugh, alright, gotta cross him off the list>>.”

The Dancing with the Stars contestant said the awkwardness didn’t last very long, and she quickly accepted Ashton Kutcher’s role as stepfather.

“It was definitely weird for a minute but I have to commend him, he was a really great stepfather and the perspective shifted very quickly,” Rumer Willis said.

“That’s when you open up your Teen Beat and then you just take him down, find someone else and put him up.”

Demi Moore, 52, and Ashton Kutcher, 37, were married in September 2005, but separated in 2011 following an Us Weekly report that he cheated on her with a woman named Sara Leal in San Diego.

However, Rumer Willis said she didn’t feel any skepticism about the relationship despite plenty of naysayers given the former couple’s age difference.

Earlier this month, The Longest Ride actor Scott Eastwood dropped a bombshell during his Watch What Happens Live appearance, when he claimed that he was actually dating Sara Leal when she allegedly cheated on him with Ashton Kutcher.

Ashton Kutcher filed for divorce from Demi Moore in December 2012, citing irreconcilable differences. The divorce was finalized on November 2013. He is now married to Mila Kunis and they have a daughter together.
