The bride-to-be is set to exchange vows with Suits actor Patrick J. Adams in the coming weeks, and she gathered her female friends over America's Labor Day holiday weekend (03-05Sep16) to help celebrate her bachelorette party with a European getaway.
On Sunday (04Sep16), Shay took to Instagram to share her joy at being invited to take part in the festivities.
"SO excited to spend the week celebrating the most beautiful, smart (seriously, it's scary) and amazing person I know!" she gushed alongside a photo of Bellisario. "Let the bachelorette festivities commence!"
In other pictures shared online, the ladies all wore matching red and white baseball tops bearing the phrase Bellisario Gets Booted, while also donning flower crowns as they prepared for the flight to Greece.
Troian and her beau became engaged in February, 2014 after three years of dating. They have kept details about their big day under wraps, but with the bachelorette party photos, it appears the nuptials will be taking place sooner rather than later.
Adams recently told Entertainment Tonight the couple is eager to keep its wedding date and venue a secret until after the fact.
"We're going to make sure that everyone finds out about that long after it happens," he said last month (Aug16). "That's kind of our game plan... but obviously we're both incredibly excited. Once it does, we'll make sure that the world knows."
