RACHEL RILEY, who is a favourite on Countdown, joked about her “knockers” as she took part in a Stand Up To Cancer campaign which was aired on Channel 4 last night.
Rachel Riley, 32, slipped into a red hot dress as she featured in a segment about women checking their breasts for the fundraiser.
The Countdown star looked incredible in the skintight number which boasted a deep plunging neckline.
The low-cut design allowed Rachel to show off her ample bust as the frock clung to her sizzling curves.
Rachel appeared in a witty clip where many female celebrities spoke about different terms for breasts in a light-hearted manner.
The video was aired to encourage women to check their breasts for any lumps and to undergo screenings which detect breast cancer.
In the clip, Rachel said: “Knockers, I found knockers hiding in there.”
She replied: “Yep that’s good for an eight from the old english ‘kanockian’ and using both k’s too which isn’t easy.”
