Producer Shonda Rhimes confirmed the eagerly awaited, television event by tweeting a photo of a script page featuring the names of Washington's Scandal and Davis' Murder characters -- Olivia and Annalise.
"People. It's happening. @petenowalk, you ready for this? #TGITCrossover #HowtoGetAwaywithScandal," Rhimes captioned the image.
"Hey Ms @violadavis check it out. This spot look familiar?! Where are you?" Washington wrote, alongside a picture of her dressed as Olivia and sitting on a bench outside of a courtroom that appears in Murder.
Scandal co-star Tony Goldwyn re-tweeted a link to a Deadline.com story about the crossover, asking: "And guess who got to direct this one! (hint: he used to be POTUS) #Scandal #HTGAWM."
It is unclear when the episodes will air.
