Iaconetti and Haibon were all smiles Friday as they kissed and flirted at the event. Haibon picked up his bride-to-be, who wore a yellow dress, at one point on the red carpet.
The "Bachelor in Paradise" alums stepped out together again at the festival Saturday.
"I understand the powers of peer pressure, but I don't understand why anyone would willingly choose the club over bed, TV, and food," Iaconetti tweeted from Las Vegas Sunday morning.
Iaconetti and Haibon got engaged in June on the set of "Bachelor in Paradise."
"I don't ever want another day to go by that I don't kiss you and tell you how beautiful you are and how much you mean to me," Haibon said.

"You'd make me the happiest man alive if I had the opportunity to spend the rest of my life with you."
Iaconetti and Haibon initially met during "Bachelor in Paradise" Season 2.
The pair also appeared on "The Bachelor Winter Games" and "Bachelor in Paradise Australia," respectively, before reconnecting.
