Burke, 34, celebrated Sunday on Twitter after Remini agreed to take the role in her wedding party.
The Dancing with the Stars pro shared a photo of herself with Remini and Lawrence. She referenced Remini's Creative Arts Emmy Award nomination in the caption.
"She said yes! #maidofhonor," Burke wrote. "So excited to have you be part of such a special time in our lives @LeahRemini! We'll be rooting for you at the #Emmys tonight."
"OMG! So far so good for 34! #amilliontimesyes #imengaged #herecomesthebride," she wrote at the time.
Burke will return as a pro in Dancing with the Stars Season 27, which premieres Sept. 24.
