Louise Redknapp's pregnant glow was on full beam during a romantic getaway in Italy with her husband Jamie yesterday.

The radiant 33-year-old proudly showed off her growing baby bump as she strolled around the pool of a luxury resort of Porto Carvo, Sardinia, in a strapless black bikini and low slung skirt.

The couple, who are 'delighted' to be expecting their second child, looked happier than ever during their afternoon in the sun.

Hands on: Jamie gently caressed his wife's growing bump

'It took me four years to have Charley and so this time, after just a month, it was very unexpected. We had talked about having another baby and we kind of expected the same problems as last time.'

'When I did the pregnancy test, I nearly fell off the chair. My friend popped in and I dragged her upstairs and said, "You've got to look at this. Am I reading it wrong?"'

'I rang Jamie straight away. He was absolutely delighted.

'It was such a relief to think I wouldn't have to go through all that treatment to get pregnant again. The doctors don't know why it has been so much easier this time - it's just the luck of the draw I guess.'

Since taking time out of her solo career in 2004, Louise has turned to TV presenting and modelling.

She became the host of Clothes Show last year and has also been named the new face of Triumph lingerie.
