Former TOWIE star Lauren worked with Keith in 2013, when the pair competed in series eight of Dancing on Ice.
And having appeared in CBB herself last year, Lauren knows exactly what the house environment is like.
Taking to Twitter last night (28 January), she said: "I worked with @keithchegwin for over 4 months and he's the nicest guy! Very proud of him in the house [and] how he has kept cool. He needs be in the final."
Comedian and TV presenter Keith has come under criticism from some housemates for 'sitting on the fence' and not getting involved in the house arguments.
However, Keith lost his temper with Katie Hopkins yesterday after returning housemate Perez Hilton informed him of comments Katie had made behind his back.
Like many of us, Lauren has been glued to this series of CBB, and the reality star tweeted her thoughts on last night's episode (28 February), which saw a series of explosive rows break out following Perez's dramatic return.
Lauren tweeted: "Omg this is brilliant, they're going from one row to another - what's going on?? #CBB Nadia is making me laugh."
