Kate and William might still be awaiting the birth of their new baby, but for one royal couple the wait is over.

Model Kendra Spears, who has been known as Princess Salwa Aga Khan since she married Prince Rahim in Switzerland in 2013, gave birth to a baby boy on Saturday in Geneva, it has been confirmed.

"Prince Rahim and Princess Salwa have announced the arrival of their first child, a son named Prince Irfan, born in Geneva, Switzerland on 11 April," a statement said. "Both mother and child are in good health."

The couple officially announced back in October that they were expecting their first child, saying they had welcomed the news with the "greatest happiness."

26-year-old Kendra grew up in the US and has appeared in campaigns for Prada and Versace among others, as well as on the cover of Vogue.

We wish the happy parents all the best!
