Few pregnant women would feel comfortable on a beach in a barely-there bikini. But Rebecca Loos, 32, isn’t your average mum-to-be.

She’s a world away from the woman who claimed in 2004 that she’d had a four-month affair with David Beckham after working as his PA in Spain.

Now, with just weeks to go before she’s due to give birth to her first child with Norwegian doctor Sven Christjar Skaiaa, 35, Rebecca insists that this is the sexiest she’s ever felt.

‘I feel gorgeous,’ she beams. ‘I never thought I’d be 11st, let alone feel fine about it. But when I look in the mirror naked, I know I look fantastic.

‘I’ve put on 2st since falling pregnant. It takes time to adjust to the weight gain and having a belly and now I just find it funny. I love showing off my bump in tight T-shirts and Sven loves my pregnant body.’

Living a quiet life in Oslo, Norway, Rebecca’s now at her happiest thanks to Sven. ‘We met at Oslo airport when I was flying back to London. We had a coffee and it started from there. Every time I’m at the airport I look at the table we sat at and go all gooey.’

She admits the baby – a boy – wasn’t planned. ‘I didn’t know if I was ready to become a mum, but when are you ever ready? I believe everything happens for a reason and I wouldn’t change a thing,’ she says.

Unlike other famous mums, Rebecca isn’t too posh to push. ‘I’ll give birth naturally in hospital,’ she says. ‘If all goes to plan, I want to push him out.’
