Demi Moore and Ashton KutcherWill a few text messages spell the end of Demi Moore and Ashton Kutcher's 5-year marriage (the pair celebrate their anniversary on Friday).

According to this week's Star, Kutcher has been having an affair with 21-year-old Brittney Jones, who shared private text messages from the actor with the magazine. The magazine has now given PopEater exclusive access to their communications.

"When's the next time you're gonna have an empty house?" Brittney wrote to Ashton.

"Not sure," he replied. "Maybe the end of the month." He then added, "I'm w/ my daughter."

"Ashton was really paranoid," Brittney told Star about the texts.

Last week, Star was the first to report the affair, claiming that Jones and Kutcher had sex on a couch while Demi was filming 'LOL: Laughing Out Loud,' her upcoming feature with Miley Cyrus.
