Kate Middleton's Blue Coat Sparks Baby Boy Rumours

Some people are probably already placing bets that Kate Middleton will give birth to a baby boy simple because of her recent fashion choices.

On Monday, Jan. 19, the Duchess of Cambridge wore a pale blue Seraphine coat at the opening of the Kensington Aldridge Academy, causing some to speculate that she's expecting another little prince. (Note: blue isn't just for boys anymore, folks.)

The 33-year-old mum looked gorgeous in the "Natasha" coat, which sold out immediately after Catherine's appearance.

The coat, which features faux pockets and buttons that stop at the waist, is similar to a baby blue double-breasted Matthew Williamson coat she wore last year and a powder blue Alexander McQueen coat that she also wore several times in 2014.

But for those who are convinced that the Duchess is hinting at the gender of her baby, remember that when she was pregnant with Prince George she wore a variety of colours, including peach, pink and yellow.

Secretly we're hoping that Kate has a girl so she can pass on her fabulous outfits to a little princess!
