Atomic Kitten's Jenny Frost shows off her sizzling bikini body on a family holiday in Greece

Atomic Kitten singer Jenny Frost certainly didn't live up to her surname as she showed off her sizzling figure on a sweltering holiday in Greece.

The 30-year-old singer and her DJ fiance Dominic 'Dom T' Thrupp are vacationing with their baby son Caspar in the Greece's largest island Crete.

Despite giving birth just nine months ago, Jenny has slimmed down to her pre-baby shape.

As she frolicked in the pool with Dominic and baby Caspar, Jenny showed off her svelte, tanned figure in her tiny stripy bikini.

In the sweltering temperatures of Crete, the family couldn't tear themselves away from the refreshing, cool water of the hotel swimming pool.

While glowing Jenny continued to work on her already dark tan, she made sure baby Caspar was covered in plenty of sunblock and a hat to keep the sun off his face.

Jenny and Dominic couldn't take their eyes of their baby son as they watched him enjoy his first experience of water floating about in an inflatable seat.

The Whole Again singer and long-term love Dominic welcomed Caspar last October after a worrying pregnancy.

During a pregnancy scan, doctors highlighted a possible abnormality on the baby, which lead to weeks of anxiety for the expectant parents.

She said: 'At my 20-week scan a development problem showed up with Caspar's head, which was a huge concern and very scary.

I have the best friends and family in the world but I like to deal with things on my own, so I went back into my shell and sat on the sofa, watched TV and ate.

'I just blocked everything out and said my prayers, and we got the all-clear at 27 weeks. We kept as positive as we could and, thankfully, Caspar's perfect.'

Since giving birth to Caspar, Jenny has turned her back on the London party scene in favour of quiet nights in.

Jenny, who is part of London's Primrose Hill set alongside Kate Moss, Davina Taylor and Sadie Frost, admits she does get the occasional night out, but doesn't go as wild as she used to.

She said: 'Before I got pregnant, I was the most irresponsible person in the world. I liked to get drunk and party but I changed overnight. Having a baby has completely transformed my life.'

As well as getting to grips with motherhood, Jenny has also turned her hand to TV presenting and hosted the BBC Three show Snog, Marry, Avoid.

Meanwhile, Jenny is still singing with Atomic Kitten as festival gigs up and down the country.

Despite the pop trio - comprising of Jenny, Liz McClarnon and Natasha Hamilton - announcing a hiatus in 2004, they returned to the performing scene last year and in January released the single Anyone Who Had A Heart.
