The high street maternity brands that celebrities adore

When it comes to finding stylish maternity outfits, celebrities and royalty certainly have a lot of choice. But it isn't always designer labels that they choose to dress their growing bumps.

Over the years, everyone from the Duchess of Cambridge to Natalie Portman have been spotted out and about in some the world's most popular high-street brands - making it all the more easier for us to replicate their fabulous on-trend looks.

From American Apparel to Asos, Topshop to Seraphine, take a look through at the brands that are dressing our favourite stars while pregnant... 

Kim Sears recently announced her second pregnancy with husband Andy Murray. The 29-year-old certainly knows how to dress her bump in style and turned heads in a fashion-forward floral Topshop blouse while cheering on in the crowds at Wimbledon.

Kim Kardashian is a fan of American Apparel - and looked effortlessly cool in a grey version of the brand's jersey Ponte Tank dress, which she teamed with nude sandals from Alexander Wan and oversized shades.

While pregnant with Princess Charlotte, Kate looked fabulous in a black and white polka dot wrap dress from high street favourite Asos. Looking as stylish as ever, the Duchess teamed the design a simple black jacket, clutch and leg-lengthening heels. 

When visiting the Harry Potter film studios, The Duchess of Cambridge, then pregnant with Prince George, wore a £38 polka dot dress from Topshop, which she teamed with a black jacket. The simple monochromatic design was sold out online the same day. 

Natalie Portman looked radiant as she graced the red carpet at the Academy Awards Nominee Lunch in LA, in a black dress from Topshop. The ultra-cool bat wing design cost just £34, and looked complete with a pair of simple black flats. 

Back in December 2015, Princess Victoria of Sweden drew fashion inspiration from the Duchess of Cambridge's enviable wardrobe, opting for a Seraphine maternity dress which the Duchess wore when she was pregnant with Princess Charlotte. The Swedish royal's dress featured a pleated skirt, which she matched with navy earrings, a clutch bag and suede shoes.
