Evan Bass and Carly Waddell tied the knot at Vidanta Nuevo Vallarta resort near Puerto Vallarta, Mexico, on Saturday, and the couple -- who got engaged during the third season of Bachelor in Paradise -- were joined by a number of fellow members of Bachelor Nation.
The couple exchanged vows in a beach-side ceremony -- officiated by Bachelor host Chris Harrison -- surrounded by friends, family and their fellow reality stars.
Among the numerous former Bachelor and Bachelorette stars that attended the romantic nuptials were Jade Roper and Tanner Tolbert, Shawn Booth and Kaitlyn Bristowe, Ashley Iaconetti and her ex, Jared Haibon, and twins Emily and Haley Ferguson -- who both competed for Ben Higgins' heart on season 20 of The Bachelor.
Recent Bachelor star Nick Viall and his fiancée, Vanessa Grimaldi, were also among those who flew out to attend the ceremony.
The morning of the big day, Bass shared a super sweet snapshot to his Instagram story, showing two hotel room towels rolled to look like swans kissing (with one even wearing a veil) and rose petals strewn across the floor.
Bristowe -- the star of the 11th season of The Bachelorette -- also shared some photos to Instagram, including this hilarious pic she snapped of Tolbert and Haibon in the airport, which she captioned, "So many ex boyfriends."
Booth, Bristowe's fiance, snapped a pic of his ladylove sitting across the aisle on the flight, in front of Tolbert and Roper. He joked in the caption, "So how'd you guys meet?"
Bass -- who has three sons from a previous relationship -- proposed to Waddell during the season finale of Bachelor in Paradise last year.
ET sat down with the cute couple in January, and they opened up on what life was like after their whirlwind TV romance.
"I was really nervous going home after Paradise because I was like, 'What is my life going to be like? Are the kids going to like me?'" Waddell admitted. "It's just been so easy. The boys were so kind to me from the moment I met them, and it's gotten better and better and better. We all really love each other."
The couple's luxurious beach-side ceremony was covered from every angle by video cameras. A source recently told ET that the wedding was originally intended to be aired as part of the fourth season of Bachelor in Paradise, before production was suspended amid "allegations of misconduct," stemming from an alleged incident between contestants DeMario Jackson and Corinne Olympios.
