Lucy, 41, told the magazine the last few years have been an unexpected whirlwind - meeting and marrying her husband Richard Taggart, and having their elder daughter Bessie, born in 2007, now followed by Rosie, born three months ago.
She said: "If someone had told me a year ago that I would have another baby, I wouldn't have believed them.
"In fact, the last six years have turned out to be like the best dream ever.
"I would never have imagined when I boarded a flight as a resolutely single woman on a trip to Dubai that I would end up falling in love, getting engaged, then married and pregnant, within the space of nine months.
"Now here I am, six years down the line, with a gorgeous husband and two fabulous little girls."
And Lucy admits she's considering cosmetic surgery to regain her pre-pregnancy figure.
"I put on a lot of weight with Rosie, so I'll need a few sessions with a personal trainer," she said.
"I'm also booking in some Botox for around my eyes and forehead.
"And going under the knife scares me, but after breastfeeding two children I'm seriously thinking about having a breast lift for my next birthday."
Have you ever been tempted to have botox or cosmetic surgery after sleepless nights and breastfeeding?
