” I will miss. It’s nowhere near as good as non-celebrities, ”nodded for a second.
“Oh, I’m not that enthusiastic, I can record it and quickly move these songs forward,” said a third.

Denise Van Outen and her partner Eddie are also returning, as are Iain Stirling and Laura Whitmore and Eamonn Holmes and Ruth Langsford.
Another commented, “I prefer to watch non-celebrities more down to earth and nothing real against celebrities. Just my choice ”
“Prefer normal people like Jenny and Lee and not the fake Lorraine and she says it’s okay,” another moaned.
“If you want great ratings on Channel 4, give Jenny and Lee your own show,” another fan of the show insisted on Facebook after confirming the lineup today.
