Carly and Evan, who announced they're expecting their second child back in May, sat onstage with their daughter Isabella "Bella" Evelyn, and Bachelor in Paradise host Chris Harrison got the ball rolling on the couple's big gender reveal.
"So, a little something extra for Bachelor Nation -- you guys have allowed us to do the gender reveal," Chris said.
"That's right!" Evan exclaimed.
"That's right!" Carly agreed.
Chris then revealed he was aware of whether Carly and Evan had a son or daughter on the way.
"I know... because I know everything. That's the way this works," Chris said with a laugh.
A staffer then wheeled out a massive faux cake with blue and pink frosting all over it.
"Alright, are we ready to find out if it's a boy or girl?!" Chris yelled.
The audience cheered, "Yes," loudly and then counted down from five seconds.
