Working mother: Myleene Klass, at the Classical Brit Awards last night, has revealled she only gets four hours sleep a night

The former Hear'Say singer stole the show as she arrived to present the nominations for the Classical Brit Awards last night.

The 30-year-old dazzled the crowd in a beige figure-hugging Reiss dress and matching Louboutin shoes.

She was joined by a host of other glamorous stars from the classical music world including Andrew Lloyd Webber's ex-wife Sarah Brightman, Natasha Marsh and 20-year-old starlet Hayley Westenra.

However, Miss Klass, who only gave birth to daughter Ava last August, admitted that her punishing work schedule as a TV and radio presenter and model was beginning to take its toll.

She said: "I think the 'yummy mummy' tag is really funny. I don't feel that yummy first thing in the morning or during the night feeds. Mums with multiple children - I just don't know how they do it.

"My husband is planning to extend the family in true Irish style - he is going for a whole football team.

"So many people want to be a singer but it's the lifestyle they go for. But it's also about getting up at four in the morning, doing a night feed and then going to work then getting home at midnight. It's a tough job.

"I worked so hard to get the opportunity so I have to try and pace myself. Some people look at my diary and go 'good lord what are you doing'. Other people look at my diary and work it even harder!

"Getting back in shape was not top of my priorities. I want to be a good mummy first and foremost and not worry about which bits wiggle.

"I have a lot of extra pairs of hands. I'm very lucky in that respect."

However the singer was almost upstaged by the most unlikely of guests - Sir Andrew Lloyd Webber's 48-year-old ex-wife Sarah Brightman, who arrived looking like a woman half her age.

It was announced that Sir Andrew Lloyd Webber will receive the award for outstanding achievement at this year's Classical Brit Awards.

Lloyd Webber's musical legacy includes hits such as Evita and Starlight Express which have helped him amass an estimated fortune of 750million.

He has also won three Grammy Awards, an Oscar, six Olivier Awards and a Golden Globe in recognition of his music.
