The 40-year-old actress -- who turned heads in a J Mendel gown and Stuart Weitzman shoes -- celebrated the 100th episode of the hit ABC show over the weekend, and spoke with ET about what an "unbelievable" time it is for the series, and the personal milestones she's had as the star of Scandal.
Over the show's five-year run, Washington got married to Nnamdi Asomugha, gave birth to two children, daughter Isabelle and son Caleb, and turned 40. "To go back and see like, 'Oh, that was at the beginning, or I got married right after that episode,' it is fun to go back and watch our lives unfold," Washington noted. "And to do that with everybody, like, 'That was right when Katie [Lowes] bought her house.'"
ET also chatted with Scandal creator Shonda Rhimes -- who was wearing a Dolce and Gabbana dress with pasta printed on it -- about her time working on the show. "I think every single day that we work together has been amazing, truly," she bragged. "I don't know, 100 episodes I've spent with a group of people. It's always amazing, you know, I have these great casts and I feel really lucky."
The 100th episode of Scandal, which premieres on Thursday, takes viewers to an alternate universe and explores what would have happened if Olivia didn't fix the election and Fitzgerald Grant (Tony Goldwyn) didn't become president. "It was really a fun exploration to think about who [Olivia] would be if she wasn't her," Washington said. "It was really fun, it was a nice challenge."
Last month, ET also spoke to Lowes -- who portrays Quinn Perkins on Scandal -- about being "auntie" to Washington's children. Check it out:
