Is there still hope for Ashton Kutcher and Demi Moore? 

Last weekend, the estranged spouses sought refuge in a surprising venue: Moore's ex-husband Bruce Willis' vacation home in Turks and Caicos.

"They had to get away," a source tells the new Us Weekly, on stands Friday. "Ashton's tweeting [about Penn State] was the last straw." (Last week, Kutcher unwittingly stood up for ousted Penn State football coach Joe Paterno, who was fired amid a child-abuse sex scandal. He later apologized for the incident.)

Kutcher, 33, and Moore, 49, spent time evaluating their marriage following a rocky few months that included Us Weekly's claim of the "Two and a Half Men" star's infidelities with 22-year-old Sara Leal.
