Happy Birthday, Katherine Heigl! (Again)

One might have thought one Roaring 20s birthday party at her Mom’s house would have been enough for Grey’s Anatomy birthday beauty Katherine Heigl.

One night of jazz and Prohibition-era liquor should be enough, right?

Heck no!

Keeping a flapper-type fur about her (watch out for flour bombs), Heigl was treated to a 31st birthday dinner with friends at the Desert Rose in Los Feliz restaurant by her husband, musician Josh Kelley, 28, last night.

Seattle Grace’s “Izzie” enjoyed blowing out the candles on a large birthday cake at the restaurant, which opening at the beginning of the fall and features a beautiful stained glass rose over its entrance.

Heigl’s no fool.

She’s reportedly planning on adopting a Korean orphan because she’s not into giving birth.

And here’s the reason why. You can’t party (in multiple) like a rock star when you’re all expectant with child.
