The 27-year-old supermodel and her fiancé Hermann Nicoli, who have been dating for over 10 years, are reportedly set to welcome their first child into the world in early September.

A source told E! News: "They are very happy. They plan to spend the summer in New York."

And the Victoria's Secret beauty is thrilled she's not the only one in her friendship group expecting, as her best pal Behati Prinsloo and her husband Adam Levine are also rumoured to be pregnant with their first child.

The insider added: "Candice and Behati are best friends and they are not far apart from each other in pregnancy due dates. They both have been experiencing the first stages of being pregnant together and are happy to have each other who understand. They can't wait to be mummies!"

Candice and her handsome beau got together when she was just 17 years old after they met in Paris and, after nine years of dating, finally got engaged last year.

Meanwhile, the South African-born beauty has made no secret of the fact she wants a little family of her own.

Speaking prior to their engagement last year, she said: "I would love to have children."
