Gogglebox is one of our favourite shows on TV at the moment, but fans were left shocked and surprised when one of our favourite stars was missing from our screens this weekend.

Sandra and Sandy have warmed the hearts of many since their beginning on the show, so when Sandy was replaced by Sandra's daughter last night, many questions were asked.

The fans flocked to Twitter to try to get answers as to where Sandy went, with people thinking she's either left the show for good or it was just a once-off.

It's still an unsolved mystery at the moment, but for now, here are the best Twitter reactions from the episode:

Where's Sandy?! #gogglebox
