Ellen Pompeo and Kate Walsh are making us feel so nostalgic!

The Grey’s Anatomy stars took to Twitter on Friday (May 22) to look back at one of the most iconic moments from the season one of their hit show.

“Unreal that today marks 15 years ago to the day since this little lady walked on to your screen and checked ya for screwing her husband,” Kate wrote on Twitter along with a clip from the season one finale when her character Addison first met Meredith (Pompeo), who was having an affair with her husband Derek (played by Patrick Dempsey).

Ellen then commented on Kate‘s post, writing, “”@katewalsh thank god I messed with your hubby!! Face with tears of joyFace with tears of joyFace with tears of joy it worked out well for us both!!! Love you so much and THAT scene …when your character showed up …was such a defining moment for this show. From that point on we had them hooked!!!”
