Myleene Klass Adds Glitz And Glamour To Countdown In A Series Of Cute Dresses

Myleene Klass is making a week-long guest appearance in Countdown's Dictionary Corner this week - and she's definitely injecting some glamour into the show!

The musician and mumpreneur first starred on the show last May, but made a very excited return to the C4 programme this week. And it looks like she might have worn almost every dress from her Littlewoods range in the process.

She shared a picture of herself and Rachel Riley standing next to the letters board, and both ladies looked stunning. Myleene was sleek and sexy in a bright red dress with a black trim, while Rachel was pretty in a white lace dress with black trim, which Myleene had left in her dressing room as a pressie (from Littlewoods, of course).

She captioned the pic: "Two from the top! #whoop #countdown @@RachelRileyRR."

She also shared a close-up pic with the word selfie written on the letters board behind, writing: "Couldn't resist! #selfie."

Myleene was first pictured wearing a canary-yellow dress in a snap tweeted by Countdown. She wrote: "YAY! Good to be back!"

There was another quick change that saw Ms Klass co-ordinate with the Countdown clock in a royal-blue shift dress, a snip at £69 from her Littlewoods collection. She even 'sang' the the clock's famous tune for her Instagram fans: "Dud dur, dud dur, dud dud dud dur, pooooo #countdown #graceland."

And, of course, you can't visit Countdown without having a cuddle with the host. Myleene tweeted: "*Nick Hewer klaxon*"

Looks like she's having a ball.

Myleene is a total style queen, often showing off pieces from her own line at Littlewoods. See more of her sartorial choices below:
