Jennifer LopeZ has dismissed reports she and husband Marc Anthony conceived their newborn twins via in vitro fertilization (IVF), insisting it took her years to get pregnant naturally.

The Jenny From The Block singer gave birth to son Max and daughter Emme in a Long Island, New York hospital on February 22nd. And Lopez is adamant the couple never turned to artificial insemination.

She tells People magazine, "It was natural. We didn't do in vitro, which I know was reported. Everybody assumed that because we had twins. I wanted to have a baby, but I've always said exactly what I said all those years they (reporters) asked us since we've been married: 'Well, when are you guys gonna have some kids?' 'When it happens naturally, I guess!' And that's when it happened. It was a surprise to us."

Lopez, 38, admits she often doubted whether she'd ever become a first-time mom. She adds, "You start getting older, you think to yourself, 'Maybe (having kids) is just not meant for me.' I knew there was nothing wrong with me. I knew that I could. Deep down, I really wanted it badly... (But) after one year, two years, three years... You know, you start thinking to yourself, 'Well, maybe...'"
