sunglasses Ellen Pompeo jeans car salon

Or should we say her hubby's jeans?

Ellen Pompeo stepped out in some major boyfriend jeans for a trip to the salon in LA. But hey, you gotta be comfy when you're sitting in a hair stylists' chair for all those hours!

Earlier this month, the Grey's Anatomy star was spotted hangin' out with Nicole Richie, as the two met up for a play date in Griffith Park.

Pompeo and Richie's kids had a blast playing together, and we can't help but wonder if the mom's have been planning a joint birthday party for their kids.

Stella Luna will be turning two on September 15, and Sparrow James Midnight Madden will also turn two on September 9.

Talk about the coolest joint bday bash ever!
