Former Hear'Say singer Myleene poses in a number of designs from the collection, which features a total of 25 pieces including bikinis, cover ups and dresses, while standing on the white sands of an idyllic beach with a beautiful deep blue sea in the background.

And Myleene recently expressed her excitement at launching the swimwear line for Littlewoods by posting a message on Twitter for her fans.

She wrote: 'Launching my first ever swimwear range for @littlewoods. I am VERY proud and excited. Get the fake tan out girls. #Myswimwear #strongmamas (sic).'

Speaking at the launch, she also told MailOnline: 'Through pregnancy and burgers, I've been all shapes and sizes so going up to size 20 for this collection was like the angels calling.

'I've included a white bikini, I couldn't not. But don't worry, I've made sure it's lined!'

The model was lucky enough to fly out to the Caribbean island of Antigua to shoot the photographs for the campaign in January.

And while she enjoyed beautiful sunny weather for much of her trip, Myleene had to endure a few short showers which resulted in a beautiful rainbow once the rain cleared.

At the time, Myleene tweeted a photo of her posing beneath the colourful arc in a white dressing gown.

She captioned it: 'After the rain,' which perhaps shows that she too saw it could have deeper meaning.

Good omen: Myleene Klass looked delighted to spot a rainbow as she posed in Antigua

The mum of two beamed from ear to ear as she posed beneath the positive omen.

Myleene was joined on her trip by stylist Christian Wood who she was pictured with wearing a pretty aquamarine bikini with a delicate Hawaiian inspired print.

She looked happy and healthy as she posed in a pair of large sunglasses with her friend.
