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.

Other pictures include the Grey’s cast at the Entertainment Weekly party at NYC’s The Box later in the evening.

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

Who rocked the ABC Upfronts best — ELLEN, SANDRA, KATE or SARA?

Blige, Christina Milian, Leah Rimini, Roselyn Sanchez, Emmy Rossum, Shane West, Mario Lopez, David Boreanaz, Tyrese Gibson, Pete Wentz, Mekhi Phifer, Donald Faison, and of course, the Heroes cast — Hayden Panettiere, Milo Ventimiglia, Masi Oka, and Jack Coleman.

Sitting front row: Penelope Cruz (nice Dr. Evil pose), Ashton Kutcher, Demi Moore, Grey’s Anatomy’s Eric Dane and wife Rebecca Gayheart, and America’s Next Top Model’s Eva Pigford sitting next to Russell Simmons.
