Prince George and Princess Charlotte might be looking forward to more than just one playmate! Just as the Duchess of Cambridge Kate Middleton's due to deliver her third child this month, there's news that younger sister Pippa is looking to welcome her own and firstborn!

According to UK newspaper, The Sun, the couple had made the announcement to close friends and family after a scan revealed she was 12 weeks pregnant. 

Pippa, 34, tied the knot to financier James Matthews, 45, in a church ceremony followed by an elegant glass marquee reception in May last year, then jetted off to French Polynesia and Sydney, Australia for their honeymoon.

The news isn't officially confirmed but Pippa is expected to give birth in October.
