Duchess Kate puts baby bump on display in Catherine Walker dress in Sweden

It's a royal reunion!

Prince William and Duchess Kate spent the first day of their royal tour of Sweden and Norway by grabbing lunch with the King and Queen of Sweden, their daughter Crown Princess Victoria and her husband Prince Daniel. It's the first time that William and Kate have reunited with Victoria and Daniel since their 2011 nuptials. Between baby No. 3 and Prince Harry's upcoming wedding to Meghan Markle, we think there's definitely a lot to catch up on!

As expected, Kate dressed to impress for the occasion, trading in her fur-trimmed Burberry coat and Sorel boats she wore earlier in the day in favor of an emerald green Catherine Walker dress that showed off her blossoming baby bump. She paired the look with black tights, velvet pumps and her iconic engagement ring.

The two couples went for a walk after lunch from the royal palace to the Nobel Museum and were photographed thoroughly enjoying each other's company.

Earlier in the day, William and Kate kicked off their four-day tour at an outdoor ring in Stockholm where they were taught "bandy hockey" -- a favorite sport of the locals. The Duke and Duchess of Cambridge battled it out, but despite being a keen field hockey player as a student, Kate lost to her husband by one shot.

Kate and William will continue on with their tour later this evening with a dinner at the residence of the British ambassador, where they are staying for the duration of their trip to Stockholm. Of course, we can't wait to see what Kate will be wearing next!
