AMANDA Lamb is clearly one of those enviable women who bloom when they’re pregnant, but as she happily pats her tummy, she lightheartedly indulges in a bit of celebrity bump envy.

“I’m due at the same time as the Duchess of Cambridge but I keep thinking she’s swallowed a pea.

“There’s nothing of her, perhaps she leaves her bump at the palace when she goes out!” jokes the TV presenter who found fame as the Scottish Widows model and went on to host Channel 4’s A Place In The Sun.

“I cheer myself up by looking at pictures of Kim Kardashian, who’s also due in July but who’s really showing.”

Lamb is chatting at her Surrey home and reflecting that in the space of a year she has been on an emotional rollercoaster.

She’s married, celebrated her 40th birthday, and, prior to this pregnancy, suffered the heartache of a miscarriage.

“It’s been the best of times and the worst of times,” she says. “I’ve got married to an amazing man, we already have one beautiful daughter and we just found out that this baby is a girl, which is so exciting. We’re calling her Lottie, so I hope the hospital is right!”

Last June, Lamb, married cameraman Sean McGuinness, aged 36. They have been together since 2008 and have a daughter, Willow, aged four.

Their wedding was a glamorous occasion at fashionable Babington House, Somerset, attended by celebrities including Eamonn Holmes and Ruth Langsford, Christopher Biggins, Dragons’ Den member Deborah Meaden and Bernie Nolan, as well as other friends and family.

Surprisingly, Lamb, 40, who was married previously and divorced in 2003, admits she didn’t expect to experience a romantic happy ending .

“I made a speech at the wedding – I know that’s unusual as a bride but I’m one of those people that rarely shuts up!

“I said that during my thirties there was a period when I thought I was always going to be on my own.

“About nine years ago I even came to Babington House with some friends and a wedding was going on, and I thought, ‘That’s so lovely but I’ll never have that’.I call it my Bridget Jones phase.

“But thanks to Sean,I now have everything I've ever wanted.”

The couple met while working together on A Place In The Sun, which Lamb began hosting in 2001, and she says their love grew out of friendship.

“Working together allowed us to see the good side and the bad when we were both grumpy, tired and stressed after a difficult day.

“Sean had to work away for a while after about 18 months and it was a lightbulb moment for both of us when he returned. We both realised this was more than friendship.

“His proposal, even though we’d talked about marriage, came as a complete surprise. Willow was about two and I thought we were just leaving her with her granny and having an afternoon off for tea at Claridge’s, but unbeknown to me, he’d booked a suite. He whisked me upstairs and went down on one knee.

“I’m glad we took our time to get married because we did it for the right reasons – we love each other and wanted to make that commitment.

“Also, after we had Willow,I became quite old-fashioned about wanting to have the same surname as my daughter.

“I think having a child together cements the very special bond between you but, for me, marriage has made it feel even more solid, and different to just living together.”

Shortly after their honeymoon, Lamb celebrated her 40th birthday and also found out she was pregnant, but sadly she later discovered she had miscarried.

“I had what is termed a missed miscarriage, where the baby stops growing but you still think you’re pregnant.

“It was hideous and, of course, at my age,I was devastated.I thought, ‘That was my last chance’.

“I think the misery of miscarriage is underestimated. People try to say the right thing but none of it helps.

“My star sign is Cancer, the crab, and I sort of retreated into my ‘shell’ for some weeks and grieved.

“Then I made myself get on with life and out of the blue, two months later, this baby started her journey.”

She’s only recently felt able to talk about her joy at the impending birth.

“Once you’ve had the shock of losing a baby, you feel very anxious about the next pregnancy.

“Thankfully everything’s gone smoothly and I’m finally starting to relax and feel confident that this little one is fine and thriving.”

Her second daughter’s arrival means the couple’s three-bedroom house will be bursting at the seams and inspired by her role on My Flat-Pack Home, she’s considering having a flat-pack room installed at the bottom of her garden to accommodate visiting family and guests.

“There’s no other way we can get any more space and I’m a complete fan of flat-pack since presenting the programme,” she says.

Lamb has a busy life but she takes care to ensure a healthy balance in her private life and career.

“You learn from past experience and realise it’s very important to nurture a relationship and not take it for granted,” she says.

“Sean and I make time to be together, and we’re really good at talking things through, so if there’s a problem, we sort it and don’t let it fester. Just last weekend the two of us were teaching Willow how to bake cakes and I thought to myself, ‘I’m so lucky, really lucky’.

“I have a fantastic family, a fantastic life and I’m really grateful and count my blessings every day.”
