Lee told fans that he had spotted US fetish model Cami in a branch of Slug and Lettuce on Sunday (8 February) afternoon.
Taking to Twitter, he said: "I'm such a celeb spotter, Cami Li in the house. #SlugAndLettuce."
And it seems like 41-year-old Lee wasn't about to let his observations stop there, as he went up to Cami and grabbed a photo with her!
Lee, who took part in the first series of The Big Reunion, later said: "So I had a fan girl moment. Had to be done @CamiLiModel #CBB @bbuk."
Friday's grand finale saw Katie Price crowned as the winner of series 15 of Celebrity Big Brother. Katie Hopkins was runner-up and Calum Best came in third place. Meanwhile, Keith Chegwin was fourth place and Michelle Visage came fifth place.
Cami was evicted from the house on day 27 during the live bombshell show, which saw host Emma Willis lead Cami out through a hidden door behind a mirror.
