Are Ashton and Demi over?

The tabloid covers keep coming.

Three Star cover stories, and now a People cover story, have raised alarm bells about Ashton Kutcher's alleged extramarital affairs.

As Kutcher and wife Demi Moore gear up to celebrate their fifth wedding anniversary, Kutcher has spent the past month battling rumors that he had multiple affairs and hook-ups, including trysts with a 21-year-old woman in the home he shares with Moore.

So far Kutcher and Moore are putting up a united front.

Sources tell People magazine that Moore, 47, “gushes” over husband and could be heard laughing with him on the set of her new film “The Reasonable Bunch.”

Brittney Jones is the woman who alleges she had an affair with Kutcher.

Kutcher, for his part, has denied any infidelity and has even threatened to sue Star magazine, which broke the reports, for defamation.

According to Star, Brittney Jones, 21, had sex with Kutcher, 32, this summer and saved text messages from him.

“Ashton was really paranoid,” Jones told the magazine. “My phone was broken at the time, so I couldn’t receive or make calls, I could only text.”

The texts include questions like “what are u wearing now?” and “whens the next time you’re gonna have an empty house?”

RadarOnline.com reported that Jones was “obsessed” with Kutcher “for years” before the alleged affair.

Kutcher was earlier alleged by Star to have been seen making out with a young blond woman in a popular Los Angeles restaurant.
