MYLEENE Klass returned to one of her most famous ever looks - posing on her birthday in a white bikini.
The singer and former I'm A Celeb star looked incredible as she went off for a bike ride in the skimpy outfit.

Myleene captioned the snap: "45 be like… Thank you for all your lovely HBD messages, for your support and love.
"Here’s to the next 45 years my friends. I’m off for a bike ride, a swim and some cake!"

Mum-of-three Myleene rose to fame in the pop group Hear'Say before becoming a TV presenter, including a brief stint on Loose Women.
In 2006, she appeared in the I'm A Celeb jungle and provided the series with one of its most iconic scenes.
Her turn in the camp waterfall wearing the white bikini is still referenced as one of the show's best-remembered moments.
The bikini was later auctioned for charity to help victims of the collapse of Farepak and its hampers scheme, raising £7,500.
Mylene now has her own fashion line with Next, and the swimwear she was wearing in her birth snap is part of the collection.
She told fans: "Before you ask, white bikini out 16th April."
The star will soon return to I'm A Celeb for its 'all stars' series in South Africa.
The special show - made up entirely off former contestants and pre-recorded at the end of last year - will air later this month.
