Not everybody is happy that Pompeo has been posting Instagram photos of her reunions with past Grey's co-stars, including Thursday night's surprise guest. As one fan tweeted, "Meredith Grey can f*ck off with her spoiler posts. Like give us at least 24 fucking hours! Ughhhhhh yeah @EllenPompeo I’m big mad lol." Pompeo responded: "Cmon bruh ...Meredith Grey has been through a lot ... and just an FYI ..my name is Ellen Pompeo and run her Insta so that’s on me."
