Royal fans were sent into a frenzy over the news that Duchess Kate was expecting her third royal baby.
However, it looks like there could be another announcement soon, as rumours abound that Kate's sister Pippa is pregnant.
Just months after their 'society wedding of the year,' Pippa, 34, and her hedge-fund manager husband James Matthews, 42, are said to be expecting their first child.
A Middleton family friend told Us Weekly: 'It's long been a dream for Kate and Pippa to be pregnant at the same time. To share that would be amazing.'
Furthermore, a close pal told New Idea that all of Pippa's friends are convinced that she's pregnant.
'In the lead-up to her wedding, Pippa was telling everyone that she and James were going to start trying as soon as they got married,' says the source.
The news will no doubt delight Kate, 35, despite the sisters enduring a frosty relationship recently - Kate was said to have been less than impressed at her younger sister's lack of discretion during several interviews over the past few years.
However, since Pippa's wedding in May, sources say relations have thawed, with Pippa becoming a regular visitor at Kensington Palace while Kate recovers from the severe morning sickness that's hit her once again.
