There's a lot to be exposed about Ashton Kutcher's one-night-stand, including a home-made sex tape the mistress shot when she was just 19-years-old, RadarOnline.com has exclusively learned.
"She was definitely into it," Jones' ex -- and the film's co-star -- admitted to RadarOnline.com.
"We were together at the time so we made short little clips of us having sex in various positions."
The former lovebirds dated on-and-off for a year before splitting about six months ago when Brittney "cheated on me", he said.
It's the latest twist in the cheating scandal that has erupted since Jones went public about her one night tryst with the married Hollywood heartthrob and star of That's 70's Show.
As RadarOnline.com revealed, the woman who threatens to bring down Kutcher's marriage to Demi Moore has a history of wild partying and posing provocatively - as these nude photos show.
"She definitely is a hard partier and always drank a lot," said one source, who knows her.
According to the confidante, Jones has been "couch surfing" from house to house, living and seemingly leaching off the various men in her life.
"She seems to have had a falling out with her mom and sister and just lives off of her boyfriends," the source said.
While Kutcher has denied he cheated on Moore, his wife of five years, those close to Jones believe the explosive revelations are true.
Said one friend: "She once told me he Kutcher was by far the number one celebrity she'd like to have sex with."
