Ok, who didn't see this one coming?
But that didn't last long as Penn and his wife quickly made up just about a month after that and called off their divorce.
Tellingly, though, this past February, when Sean won an Oscar for his performance in Milk, he neglected to mention his wife in his acceptance speech because there wasn't "enough time."
Then, just last month, reports were that Penn had been caught hooking up with Natalie Portman, which sources close to Portman denied at the time.
And, now, according to TV's Extra, Penn filed for “legal separation with minor children” last Friday, just three days before the couple's 13th wedding anniversary.
Wonder if this time it'll be final?
