ET breaks down the Duchess of Cambridge's latest looks!

Blue seems to be Kate Middleton's color of choice as of late!

Ever since the Duchess of Cambridge announced she was expecting her third child with Prince William back in September, we've noticed that the 36-year-old royal has seemingly taken an intense liking to the regal hue. Which got us thinking: Could this be a giant clue that baby No. 3 is a boy?

Kate and William have yet to confirm the sex of their third child, but judging by the brunette beauty's recent fashion choices, we wouldn't be surprised if Prince George, 4, and Princess Charlotte, 2, will soon be siblings to a baby brother. In the meantime, ET's breaking down all the times Kate has worn a shade of blue over the last few months.
