Kate Middleton Has Helped Maternity Label Seraphine's Good Fortunes Soar

The Duchess of Cambridge, Kate Middleton, has been doing much to help maternity label Seraphine make a real name for itself in the world of baby bump designs.

The Kate effect is still in full force as the brand has just opened its third boutique on Marylebone High Street in central London.

"We have been waiting for a long time for a shop to become vacant in Marylebone, and then, finally, it did," Cecile Reinaud, the company's founder and designer told The Telegraph.

I think we got bumped to the top of the list because of the Duchess, who is a big fan of the label. There were five retailers waiting to get this space, but we got it, so we are very happy."

But Kate isn't the only famous mum who's a fan of the label. Rumour has it Angelina Jolie, Sienna Miller and Halle Berry are all avid wearers!

K-Middy has been making headlines recently as she was spotted sporting a few silver strands in her flowing brown locks, leaving everyone questioning whether she'll go grey gracefully of whip out the hair dye bottle.

What do you reckon?
