Myleene Klass will feature on Sky HDTV’s new TV testcard. The original testcard, which featured a young girl playing noughts and crosses, aired on terrestrial TV channels when programmes ended for the night, but I think we can all admit that Myleene will be a definite improvement!

Myleene commented: “I’m really excited to be the face of the Sky HD testcard and to be taking part in a little piece of TV history.

“For me, the card evokes nostalgic childhood memories of staring at the TV waiting for Playschool.”

Chris Johns, chief engineer at Sky, added: “Myleene looked great in the jungle and looks even better in HD.”

HD-enabled viewers can see the Klass card on Sky channel 268.
