The Masked Singer season two only has a handful of characters left in the competition.
Seven celebrities have already been unmasked, find out who has been revealed here, and five will go head-to-head this weekend for a place in the final.
Still in the running is Badger, Dragon, Sausage, Robin and Harlequin, and new odds from Betfair show Robin is the new favourite to win the show.
Previously it was Badger in the top spot, but the popularity of Robin now make him 6/4 most likely to win The Masked Singer UK having seen his odds slashed from 4/1 last week.
Robin is followed by Badger 2/1, Sausage 4/1, Harlequin 5/1 and Dragon 16/1.
Betfair spokesperson Sam Rosbottom said: "The competition is really hotting up now as we get to the final five singers, with armchair sleuths convinced they clearly know who is behind each of the masks.
"Sheridan Smith has the shortest odds at 1/4 to be sausage, followed by Aston Merrygold at 1/3 to be Robin and Gabrielle who is 1/2 to be Harlequin. Punters are a bit less confident in Ne-Yo at 4/5 to be Badger and Courtney Act who is 10/11 to be Dragon, but with more clues unveiled each week, they seem to be excelling as amateur Sherlock Holmes'.
"Meanwhile there is a new favourite to win the show in the form of Robin, whose clearly-trained professional singing voice has vowed viewers into slashing his odds from 4/1 to 6/4 to be champion."
