Myleene Klass is making a guest appearance on hit TV quiz show Countdown.

The 35-year-old classical musician, model and mother-of-two joins word expert Susie Dent on the Channel 4 show this week (from June 17).

Myleene has apparently been a big fan of the show since she was a student and was really excited about joining Susie and host Nick Hewer to film six episodes at the official studio at Media City in Salford.

The former Hear'Say star has another TV presenting job in Blue Peter - You Decide!

The spin-off CBBC show sees Myleene and Eamonn Holmes as judges helping in the hunt for a new Blue Peter presenter.

The single mum, who split from husband Graham Quinn last year, recently won the Glamour Women of the Year Awards' entrepreneur gong.

Presenter and former I'm A Celebrity contestant Myleene has launched everything from a swimwear collection to a baby clothes range.
