Ahem. Ya think their stylists coordinated their outfits?

Most of the Grey’s Anatomy stars made it out for the ABC Upfronts at NYC’s Lincoln Center on Tuesday — Ellen Pompeo, Sandra Oh, Kate Walsh, Sara Ramirez, Eric Dane (with wife Rebecca Gayheart and Justin Chambers (with wife Keisha).

Kate, who’s getting her own Grey’s spin-off series called Private Practice, announced her engagement to Fox Studios exec Alex Young at the Upfronts.

Noticeably missing from the soirée were all parties involved in the Grey’s war: Isaiah Washington, Patrick Dempsey, T.R. Knight and Katherine Heigl.
