Rumer Willis had a teenage crush on Ashton Kutcher before he started dating her mom, Demi Moore, in 2003, USA Today has learned.

The "Dancing With The Stars" contestant even had Kutcher's posters on her bedroom walls; something she admitted to Howard Stern in an interview on "SiriusXM" show.

"It was definitely weird for a minute but I have to commend him. He was a really great stepfather," Willis said of Kutcher.

"The perspective shifted very quickly," the 26-year-old dancer added.

Willis was then asked how she stopped herself from having the hots for Kutcher, who was then 25 years old.

"You open up your Teen Beat, take him down and find somebody else to put up. I feel like I told my sister that at one point like, 'Man, gotta cross him off the list,'" she explained while laughing.

Having Bruce Willis and Demi Moore as parents was not easy for the "90210" actress, but she said she got used to it at an early age, US Weekly reported.

The "Sixth Sense" actor and the "G.I. Jane" actress got married in 1987 but filed for a divorce in 2000. Despite what happened, Willis and Moore remained good friends.

"It's something that I commend them for so much," the "Hawaii Five-0" guest star shared. "They made such a huge effort that we never had to split up birthdays or vacations."

"We literally would all go together. They had this weird thing where they literally just became friends," she added.

Meanwhile, Willis didn't feel any resentment when her mom dated the "What Happens in Vegas" actor, following the divorce with her dad. Instead, she was ingrained and very supportive of their relationship.

"I feel like I was kind of impressed like, 'Yeah girl, get it,'" she said.

Willis and Kutcher kept their communication open even after Moore divorced him in 2013. In fact, she revealed that she contacted the "No Strings Attached" actor in November, after the birth of his and Mila Kunis' daughter, Wyatt, E! News reports.

"I reached out to him when he had the baby, which is so awesome," Rumer Willis said.

"I saw photos of her [Wyatt]," she added. "She's very cute."
