Pippa Middleton had a fun weekend in Austria at a wedding and partied into the evening, while her pregnant sister Kate Middleton's due date came and went. Was the due date just a hoax to trick the media?

Pippa was in Vienna, Austria attending the wedding of Chanel ambassador Caroline Sieber and Fritz von Westenholz, The Huffington Post reports. The 29-year-old wore a bright coral dress and jacket in a paler hue by Matthew Williamson, paired with nude heels and hat.

She was later spotted partying in Vienna wearing patterned purple and black pants, a black shirt, and cream blazer, sporting a huge smile.

So why was Pippa across the continent partying it up, right after Kate Middleton's due date of July 13, sans baby birth?

Speculation from the media and fans are starting to think the royal couple tricked the media to throw them off, thereby easing the pressure off Kate. After all, her husband Prince William spent the weekend playing polo with Prince Harry hours away from his pregnant wife, Celebrity Dirty Laundry reports. He didn't stop his charity activites with the concern of his wife going into labor.

But we know Kate is one step closer to giving birth to the royal baby, as the Duchess of Cambridge has moved out of her parents' house into a cottage closer to St. Mary's Hospital, where the mom-to-be is planned to give birth, Hollywood Life reports.

The Nottingham cottage is on the grounds of Kensington Palace in London, and is right across town from the hospital.

Even though Prince William spent the weekend playing polo in Gloucestershire, the Duke has a helicopter on standby to fly him to the hospital the minute he gets word that his wife has gone into labor.

Now all we can do is wait for the big day.
