Erm, it's not everyday you come across a celebrity who forgets what show they are on.
EastEnders actress Laila Morse made a teeny, tiny slip-up when she confused Celebrity MasterChef with BBC quiz show Mastermind.

The 70-year-old told judges John Torode and Gregg Wallace: "See what you have to put up with on this Mastermind!", when they quizzed her about her dessert.
Her comment was met with roll-on-the-floor laughter from both the judges, while she jokingly told the camera crew: "Cut! Cut!", after realising the slip-up.

The latest episode saw celebrities Laila competing with former rugby star Neil Back, Sugababes singer Amelle Berrabah and Reverend Richard Coles.
And the internet was full of love for Laila, aka Big Mo.
Love Laila, I hope they keep her in for the comedy value alone!

Big Mo out of EastEnders is a hoot. She's the only person I know on 'Celebrity' #MasterChef.

I do love Laila Morse and she has a fabulous laugh. #MasterChefUK

Unfortunately, her competitors outshone her and Big Mo was sent packing along with Amelle.
She will certainly be missed.
