Tonight's telly: The Channel 4 Mash-Up, from 6.30pm

Channel 4 Mash Up - The Million Pound DropWe must admit, we here at TellyMix aren't avid viewers of Channel 4's Location Location Location. But we are going to tune in to tonight's special episode, hosted by... Alan Carr?

Yes, tonight Channel 4 is marking its thirtieth birthday eleven months early (it's in November) with a special night of programmes, which sees their talent swapping jobs with each other!

While Kirstie Allsopp teaches the flamboyant comedian the tricks of the trade, her partner-in-crime Phil Spencer is taking the reins at The Million Pound Drop, while usual host Davina McCall plays with her dad for charity.

Other highlights include the 8 Out Of 10 Cats boys taking on Countdown, and a Made In Chelsea edition of Come Dine With Me starring Caggie, Binky, Spencer and Mark-Francis.

You can watch one of the mash-ups that didn't make the cut below, featuring the Skins cast causing mayhem with Brendan on Coach Trip...
