Kate's maternity style: Her designer opens up about dressing the duchess, Amal Clooney and Beyoncé

Having dressed the likes of the Duchess of Cambridge and Marion Cotillard, maternity fashion designer Cecile Reinaud - the founder of Séraphine - has revealed her hopes of seeing Amal Clooneyand Beyoncépictured in some of her designs. Speaking to HELLO! from her head office in London on Tuesday, the renowned stylist shared that she has already been asked to send some of her collection to the two stars, who are both pregnant with twins. "Every time a celebrity gets pregnant, we get really excited," explained Cecile. "Stylists start to call us. For Beyoncé, we gave her this red dress but she also wanted something with sequins. She has also asked for lots of denim - we're hopeful that we'll see her rock our denim soon."

Cecile, who has stores across the world, first found worldwide recognition after Duchess Kate wore the striking magenta Jolene dress from the maternity brand in the first official photos of her and husband Prince William with their newborn sonPrince George.

The royal has since been pictured stepping out in New York wearing the Marina Maternity Coat when she was pregnant with Princess Charlotte. Discussing the "Kate effect", the designer added: "When this happens, the office gets so excited and the website gets flooded with traffic. Everyone is calling to buy the dress that she has worn. So it's a bit panic on board - in the best possible way."

She added: "The first time that it happened was just after her first pregnancy. It was this dress, which was the first official picture with Prince George. To be honest, I felt like had landed on the moon, 'Is this true? I need to pinch myself.' That was a very special moment." Over the years, Séraphine has been the go-to maternity label for a slew of A-listers - including Anne Hathaway, Gwen Stefani, Kate Winslet and Kim Murray, who have all worn the brand's designs during their pregnancies.

"Afterwards I soon got used to it because [Kate] would wear more and more of Seraphine - particularly in her second pregnancy," Cecile continued. "She wore many things for big occasions, like the first time she went to New York. You feel a sense of pride, not just for me but the whole team because we work really hard to deliver these beautiful creations and that fact that the most stylish person to picking to wear them is a huge compliment."
