Their panellist Sherrie faces off against Natasha Hamilton, Bobby Davro, Chloe-Jasmine and Stevi Ritchie, James Hill and Austin Armacost in the final tonight.
Eek! We can't wait!
It's no surprise the Loose Women ladies have been urging their viewers to vote for Sherrie, who is affectionately known as Nana Sherrie in the house.
Jane Moore, Nadia Sawalha, Andrea McLean and Gloria Hunniford all wore eyecatching t-shirts today emblazoned with Sherrie's name; just a subtle reminder to fans that tonight is the finale!
On last night's Big Brother's Bit On The Side, each finalist had 30 seconds to tell the public why they should win.
Sherrie said: "I have had a wonderful time. I haven't experienced any like this in my life. Where else would a nana get to beat a buff boy's bottom? I can't believe it!"
