The glamour model, who has 30GG breasts, is taking part in the make-under series, which is hosted by former popstar Jenny Frost.
Featuring a straight-talking computer called POD, the show aims to create "natural beauties" and allows members of the public to state whether they would "snog, marry or avoid" the contestants.
Speaking about her fashion style on the show, Reade says: "I think people remember me from Big Brother as the girl with the big boobs. I love getting my boobs out. I paid for them - I'm going to show them off.
"When it comes to make-up it's all about perfection. My mum helps with the fake tan. My style is the tighter the better, the shorter the better. I love all the attention on me."
X Factor girlband Kandy Rain will also feature in this evening's episode.
Snog, Marry, Avoid? airs tonight at 8pm on BBC Three.
