Not if but Jen!

Sky Bet predicts bitchy drama queen Jen will be the latest housemate to be booted out of the Big Brother house in this Friday's eviction, installing her as 1/33 clear favourite to go, with Rex priced at 10/1. Sky Bet also quote 5/1 for Jen to break the eviction percentage record, of 91.6%, set by BB7's Sezer Yurtseven.

Sky Bet's entertainment manager Helen Jacob said: "The Big Brother bitches are dropping like flies and yet again this week, the eviction seems a foregone conclusion, with Jen our jolly for the high jump!""

Sky Bet are also offering odds on who Jen will say she wants to win in her interview with Davina and make Luke, Bex and Dale 2/1 co-favourites to get her vote. It's 5/4 for love interest Dale to cry live on the show when Jen's name is announced. Sky Bet also quote 100/1 for Dale and Stu to get together in the house once Jen is out of the way!

Gone to the Dogs!

The heats for the Sky Bet Gymcrack start on Wednesday, with the Charlie Lister trained Fear Zafonic heading the market at 5/4. A winner of seven of his eight races to date, the son of Premier Fantasy has been in scintillating form of late and also heads the market for next year's Blue Square Derby at 25/1.

Fear Zafonic will not have things all his own way as Westmead Diver, who was second to the favourite in the Graphite UK Puppy Derby final, and the Barrie Draper trained Boherna Best, who has produced some sparkling trial times, both look to have a huge amount of potential.

Sky Bet have also put up a bonus offer for anyone who backs the winner ante-post, namely a free bet matched up to your stake (up to £50) on the winner going on to land next year's Blue Square Derby at the fixed odds of 25/1.
