Pippa Middleton has been spotted entering the Lindo Wing at St Mary's Hospital

It's almost time!

It's safe to say the royals (and their extended family) are having a real case of baby fever this year.

As well as the birth of Prince William and Kate Middleton's third child, Prince Louis in April, Meghan Markle and Prince Harry have just announced that they are expecting their first child.

What's more Pippa Middleton, the Duchess of Cambridge's sister, is due to give birth to her first child this month – and now it looks like the baby's arrival is imminent.

Pippa and her husband James Matthews were spotted entering the Lindo Wing of St Mary's Hospital, Paddington, on Monday, the Daily Mail reports. Pictures also show dad-to-be James carrying what appears to be an overnight holdall and changing bag.

We're fairly sure this trip means that baby Matthews' arrival will be any day now. The private wing is of course the same place that Pippa's sister, Kate Middleton, gave birth to her children George, Charlotte and Louis.

First time parents Pippa and James were married last year and it was announced they were expecting back in April.

It looks like all eyes will be on the Lindo Wing once again for the rest of the week as we eagerly await news of the arrival.

We can't wait to find out all the details of their new baby. So exciting!
