Myleene Klass, 46, wows in red silk gown as she attends Christmas lights switch on in Covent Garden

RADIO host Myleene Klass adds some festive sparkle as she rocks in red silk at a Christmas lights switch on.

The ex-Hear’Say singer, 46, pushed the button at ­London’s Covent Garden shopping ­district alongside The Hobbit star Luke Evans, 45.

Mum-of-three Myleene also got into the spirit of Christmas by hopping aboard Santa’s sleigh.

Although she’s not flying off, at present.

We recently revealed how Myleene flashed her rock hard abs as she headed to work in a bra top and trousers.

She credited Pilates for her toned physique.

She said: "My ONE new muscle is in utter agony from my new hobby - reformer Pilates."

Reformer Pilates - also loved by the likes of popstar Adele and actress Michelle - is a fitness practise performed on a machine, rather than a mat.

Fans were quick to comment on Myleene's look - and fashion sense - before her show.

One put: "Looking very beautiful have a great show xx"

A second put: "Your style rocks," as a third gushed: "Gorgeous."

Another then put: "You look INSPIRING and happy."
