NIKKI Webster, the curly-haired teen of Olympic and Strawberry Kisses fame is expecting her first child.

Webster, 26, who married her 33-year-old husband Matthew McMah in November last year is now seven months pregnant.

But she's told Woman's Day that while she is excited, the couple hadn't planned on starting a family so soon.

"We weren't trying," the former child star told the magazine. "So it was a beautiful surprise."

"I felt a bit strange so I went to the doctor and the first thing she did was hand me a pregnancy test. I said 'what are you talking about?' But it was positive."

McMah says he cried and was "over the moon" at the news.

It's been 13 years since Webster hit the spotlight at the Sydney 2000 Olympic Games.

She now runs two dance studios in Sydney.
