Introducing Mrs. Emily Karlsson!

After serving as maid of honor for her twin sister Haley's wedding, Bachelor alum Emily Ferguson had her time in the spotlight as she married Vegas Golden Knights forward William Karlsson this weekend.

"Officially Mr. & Mrs. Karlsson 🤍," the couple both captioned a post that appeared on both of their Instagram accounts. Us Weekly also shared exclusive images from the wedding.

The couple celebrated at Resorts World Las Vegas with guests including Oscar Dansk, Hayley and Mark Stone, Shea and Mariana Theodore, plus the bride's twin sister Haley and her husband Oula Palve.

The newlyweds said their vows on the Rose Rooftop with views of the Las Vegas Strip and were escorted by the Knights' official drum line, the DrumBots, to party in the ballroom where the maid of honor Haley and best man Mans Johansson gave speeches.

The 29-year-old Bachelor in Paradise star got engaged to her beau on Dec. 11, 2020, and while Emily and Haley had a joint bachelorette party in February of this year and a joint bridal party in May, the twins decided not to have a double wedding.

The couple have been dating since 2017, and they announced on Instagram in 2019 that they were living together in Las Vegas after Karlsson signed an eight-year contract with the Vegas Golden Knights.

"Your hard work and dedication got you here and you deserve it all," Ferguson wrote on June 25 of that year. I've been so lucky to always call Vegas my home. To now be able to call this place home with YOU is the best feeling ever. I'm so excited for OUR life together here in VIVA LAS VEGAS!"

Two days after the couple were engaged in December 2020, Ferguson shared an Instagram post with her nearly 400, followers picturing herself and Karlsson in a warm embrace.

This past June 23, Ferguson let her fans in on a few sneak peaks of her wedding via Instagram story. One follower asked if Ferguson's dog, Obi, would have a part in the wedding.

"This goofball?!?!?!?! 😍" she added to an adorable photo of Obi on her couch. "He's gonna make an appearance for sure!"
