Grey's Anatomy is "Puttin' on the Ritz" next weekend in honor of a milestone episode.

The doctors of Grey Sloan Memorial, fittingly, throw a fundraising gala which turns wildly competitive after Jackson makes a rash promise. Also, Alex reveals an emotional secret to Jo. What could it be?

Back at the hospital, Bailey’s patience is tested when she has to deal with several extremely difficult patients at the same time. Meanwhile, Shane and Stephanie handle a very busy ER by themselves.

Check out the promo for the 200th episode of the ABC medical drama below!
