Photoshopping herself into one of the snaps, she admitted “this is absolutely pathetic!!”
But she stressed that she wanted to post the photos because she was so impressed with how hard her costars in the production worked.
Her caption included: “But I loved this photo of my amazing cast so much I… photoshopped myself into it!”
“Photoshopped. Myself. Into the bloody photo!
“These guys work so hard to bring joy to everyone during Festive Season! Massive appreciation, every one of you is wonderful!”
The Strictly Come Dancing Christmas Special airs tomorrow on BBC One at 4.40pm.
