'He was sure the Secret Service was listening in on his calls from then on,' Moore said of her ex.
In her new memoir, "Inside Out", the actress recalled the time she and her three daughters -- Rumer, Scout and Tallulah -- moved into Kutcher's house while her own home was being renovated in 2003. Before their arrival, Moore said the residence was a "straight up L.A. party house".
The actress claimed that before she moved in, the twin daughters of George W. Bush Jr. had come to the home and "ended up doing bong hits at one of Ashton's parties", referring to the use of marijuana paraphernalia.
"He was sure the Secret Service was listening in on his calls from then on," the "G.I. Jane" star added.
At the time, Jenna was enrolled at The University of Texas, while Barbara was at Yale.
Kutcher himself told the story during an interview with Rolling Stone in 2003. This time the "bong" was referred to as a "hookah".
"We're hanging out. The Bushes were underage-drinking at my house. When I checked outside, one of the Secret Service guys asked me if they'd be spending the night. I said no. And then I go upstairs to see another friend and I can smell the green waiting out under his door. I open the door, and there he is smoking out the Bush twins on his hookah."
TooFab has contacted reps for Ashton Kutcher, Jenna Bush Hager and Barbara Bush seeking comment.
Other bombshell revelations in Moore's memoir include allegations of Kutcher's infidelity, the couple partaking in threesomes, and a miscarriage early on in their relationship.
She also shared the harrowing details of a rape when she was 15-years-old, preventing her mother's suicide, and her battle with addiction.
Before her marriage to Kutcher, Moore was married to Bruce Willis from 1987 to 2000. She was also married to musician Freddy Moore from 1980 to 1985. Kutcher and Moore divorced in 2013, after eight years of marriage.
