Kate Middleton's Mulberry Coat Shows Off Growing Baby Bump During Scouts Visit (PHOTOS)

While the growing baby bumps of stars like Kim Kardashian and Busy Philipps have been on full display, it feels like we haven't had substantial proof of Kate Middleton 's royal bun in the oven -- until now, that is.

The Duchess of Cambridge stepped out yesterday for the National Review of Queen's Scouts at Windsor Castle, a parade celebrating scouts who have been honored by Queen Elizabeth II herself. For the event, Kate went full-on spring in a mint Mulberry coat, Kiki McDonough earrings, her trusty nude LK Bennett pumps and a brown Whiteley fascinator. If the hat looks familiar, that's because she's worn it quite a few times before, including at last year's Order of the Thistle ceremony , a family wedding and the Epsom Derby Festival in 2011 .

But we digress. Perhaps Catherine's most eye-catching accessory was her baby bump, a sight for all royal watchers to behold. Her sizable belly reminded us that the duchess' due date in July isn't too far away. Lucky for Kate, the 31-year-old hasn't had to surrender her heels or her signature style for a more comfortable look just yet (ahem, Jessica Simpson ).

Check out Kate Middleton hanging out with the scouts below and tell us what you think of her look!
