No surprises here!

After initially announcing their split in February (and buying a new house for herself this summer), Paula Patton has finally filed for divorce from her estranged husband Robin Thicke.

Patton cited irreconcilable differences, and she wants joint legal and physical custody of the former couple's 4-year-old son, Julian.

Patton and Thicke were married for eight years, but the couple first met in high school. It was widely speculated that the two would try to work things out after Thicke's alleged infidelity, and in July the singer still seemed to have some hope that he could win his wife back.

"I actually have no idea what I'm doing," he said in an appearance on Good Morning America. "I'm just kinda flying by the seat of my pants on this one."
