Patrick J. Adams Gathers Chris Pine and His Best Friends Together for Weeklong Bachelor Party

Sorry pretty little ladies, but this is a guys’ only trip.

Just one month after Troian Bellisario enjoyed a bachelorette party in Greece with a few famous friends, her fiancé Patrick J. Adams decided to have his own celebration with some close buddies

E! News has learned that the Suits star gathered some pals together for a week-long adventure that featured a final stop at the ARIA Resort and Casino in Las Vegas.

After enjoying some pool time, Patrick and his friends including Chris Pine, Brendan Hines and more headed to OMNIA nightclub inside Caesars Palace where they enjoyed the music of resident DJ Calvin Harris.

An eyewitness tells E! News that the groom-to-be looked relaxed and happy to be enjoying a guys’ night out and was in “high spirits” throughout the evening.

Friday night’s activities come after the group traveled across the country for a variety of events and unforgettable experiences. Whether attending the Austin City Limits Music Festival, stopping by the Grand Canyon or enjoying the great food in New Mexico, this group made the most of their getaway.

“End of days. One last night. @arialv #manfestofdestiny,” Patrick wrote on Instagram before ending the trip. “Closing night. Calvin Harris. Why not? #manfestofdestiny.”

Back in February 2014, reports surfaced that Troian and Patrick were engaged. Since then, the couple has been quietly planning their dream day when not working on their successful TV shows.

“We want to find a place that we want to get married,” Patrick teased to E! News’ Marc Malkin at the 2015 Toronto International Film Festival. “That’s the most important thing to us and I think we sort of found it but we’re not willing to commit just yet.”

And for all those curious to know what Troian will be wearing on her special day, Patrick isn’t ready to give all the details just yet. He is, however, absolutely confident that she will look stunning.

“It might be a very off the grid wedding,” the Suits star teased. “It may involve more sweaters than dress, but it will be beautiful no matter what she wears.”
