Dutch supermodel Doutzen Kroes, one of the Victoria's Secret Angels, says she is pregnant with her first child.

On Wednesday, Kroes announced at the Dutch TV program RTL Boulevard that she is on the 13th week of her pregnancy.

"Yes, I'm going to be a mother," she told the program over the phone from New York.

"It sounds so special. And I am very glad that I can finally share it with you."

According to RTL, the baby's father is the 25-year-old model's boyfriend, Dutch DJ Sunnery James.

Kroes said that she and James found it hard to keep the news to themselves and wanted to let everyone know about it when the test results were out. Their parents and close friends were the first to know about it.

She adds that Victoria's Secret was "very happy" for her.

"I had to tell them very quickly, because every millimeter that I gain or lose affects them," she said.
