Glowing Myleene Klass shows her pregnancy curves in all their glory in a white bikini

Like most pregnant women, Myleene Klass is getting used to her ever-changing body.

But as she relaxed by the pool at her Los Angeles hotel, it looked like the presenter was enthralled by her pregnancy curves.

During her five hour sunbathing session, the 32-year-old repeatedly fiddled with her bikini top, which was struggling to contain her ample cleavage.

The former Hear'Say singer spent a few days in California on a working holiday, where she presented the red carpet arrivals at the BAFTA Britannia Awards on Thursday night.

With lines to learn, Klass decided to make the most of her time in the sun and went through her script by the pool.

And she kept up her beachwear tradition by opting for a white halterneck bikini - which looked remarkably similar to the one she wore in Marks & Spencer adverts when she was expecting her first daughter Ava three years ago.

Of course, Myleene famously resurrected her career with a white string bikini on I'm A Celebrity... Get Me Out Of Here! four years ago.

Before going to work at the Britannia Awards on Thursday night, Klass posed a photo of herself in a bikini on her Twitter page, saying: 'By the pool learning my lines for tonight. Unreal...

'Red carpet for Britannia awards! Lines nearly learnt. Nearly. Err.

'Righto. Frocked up and ready to roll. First interview with the Fryster. Gonna hug him.'

At the glitzy bash, Klass interviewed a host of stars including Jeff Bridges, Dakota Fanning, Marion Cotillard, Jane Lynch and Carey Mulligan.

Displaying her growing belly in a black and red strapless gown, Klass cuddled up to fellow Brit Stephen Fry for a photo for her Twitter page.

She also posed alongside Bridges - who she nicknamed 'Santa', House actress Olivia Wilde and Kevin Spacey.

After a couple of hours mingling with the stars at the Hyatt Regency Century Plaza, Klass then headed off for the after-party.

Signing off on her Twitter: 'Top night. Fav people, Michael Sheen, Jane Lynch (Sue Sylvester) and Carey Mulligan. Have changed into my flats. Off to the party!'

Klass announced in September that she and partner Graham Quinn were expecting a sibling for three-year-old Ava in March.

Her pregnancy came after the couple spent 18 months trying to conceive.

Klass said this week she is looking forward to finding out the baby's sex at her 20 week scan.

She said: 'I don't know what the flavour is yet but I am going to be finding out. It's funny when you say it ruins the surprise, but the surprise is like a tomato or something. It's only going to go one of two ways, right.'
