Eric Johnson and Jessica Simpson

Jessica Simpson has "always had a very healthy sex life" with her husband.

The Weight Watchers ambassador, who has two children, Maxwell, two, and Ace, 18-months, with husband Eric Johnson, says he even made her feel very sexy when she gained 70 pounds during her pregnancies.

The 34-year-old singer said: "My husband and I were looking at old pictures recently, and I asked him, 'Babe, why didn't you tell me to put the brownie down?' He said, 'You looked great.' He's always loved every curve on my body. And we've always had a healthy sex life."

Despite being happy with her curvier figure, Jessica, who was previously married to Nick Lachey, decided to lose weight because she wanted to "look healthy" on her wedding day last July.

She explained: "I worked really hard because I wanted to appreciate being in a wedding gown again. I wanted to enjoy it like I did the first time. But I didn't have a weight goal; I just wanted to look healthy."

The blonde beauty now maintains her trim figure by exercising five times a week and admits she is unlikely to have any more children.

Asked if she is planning to have another baby, she told the January issue of InStyle magazine: "I don't think so. Having two kids back-to-back was hard on my body. But if I do have more, I wouldn't want them to read this and think they weren't wanted!"
