Sean Penn -- Charlize Who? Gives Minka Kelly Birthday Dinner of a Lifetime

Sean Penn and Charlize Theron called it quits just 2 weeks ago, and he's already doing his laundry with another hot chick.

These pics were taken last Tuesday at French Laundry, the uber-fancy/delicious/exclusive restaurant in the Napa Valley. Sean was celebrating Minka Kelly's 35th birthday, along with 3 other people.

They were by no means hush hush ... people at other tables heard Sean tell the other 3 he and Minka met at a Haiti charity event.

They had a feast to end all, with a chicken with the feet still attached, truffle mac and cheese and a birthday cake. The people at Sean's table, along with others in the restaurant, serenaded Minka to "Happy Birthday."

Sean picked up the tab ... and it was pricey.

Minka has not mentioned Sean, but after the dinner she Instagrammed, "Birthday festivities off to a pretty magical start."
