The stars have descended at Trafalgar Square to launch Dragon Den's star Theo Paphitis 'Tea with Theo' project, which sees a giant Red Nose Day teapot - 8ft 4inch to be precise!
Lauren couldn't resist posing for a snap with Jake before getting on with the campaigning.
Taking to Instagram, former TOWIE and Celebrity Big Brother star Lauren, said: "Me and the ledge Jake #Max working today for comic relief #Trafalgarsquare."
Strictly Come Dancing star Jake, who recently took part in EastEnders' well-received 30th anniversary live week, was all smiles as he posed for the photo.
Lauren and Jake were also joined by X Factor star Matt Cardle, and the stars all posed in front of the massive teacup!
