It seems that British royalty and Hollywood royalty think alike!

Expectant mom Kate Winslet flaunted her gorgeous baby bump sans husband Ned Rocknroll at the London Film Festival premiere of her new film "Labor Day" on Monday wearing a dress designed by Kate Middleton favourite, Jenny Packham.

The 38-year-old, who also wore Packham to TIFF 2013, took a risky leap in the deep v-neck red gown which showed off her yummy mummy curves and featured Swarovski crystals around the neck and bust. (And who said moms can't dress with style?)

The "Divergent" actress (and newly minted Vogue cover girl) complemented her dazzling look with De Beers earrings, a diamond bracelet, a black satin clutch and Christian Louboutin peep-toe heels which were mostly covered by the red carpet-sweeping gown.

Designer Packham is popular among celebrity moms-to-be having outfitted not only the Duchess of Cambridge while she was pregnant with Prince George but also Angelina Jolie and Elizabeth Hurley.

With such a huge celebrity fanbase, we have to wonder whether Kate Winslet and Middleton ever get together to talk maternity wear secrets. We sense play dates at the royal compound in the future!
