Fans, contestants and familiar Bachelor Nation faces took to the comments to let their thoughts be known on the change.
"@lancebass dance party or nah?? 🔥" contestant Connor Brennan, who appeared on Katie Thurston's season of The Bachelorette, wrote.
Contestant Tammy Ly said she "wouldn't have it any other way."
"Not the same without Chris Harrison😢," one fan lamented, a sentiment echoed by many other fans in the comments.
Former BIP contestant Adams — who became the show's bartender and serves as the "Master of Cocktails & Ceremonies" — will also reportedly host an episode.
Earlier this month, Adams told Entertainment Tonight that the new season will have a "different vibe" and that "everyone's going to be in for a really fun ride, and then I'll be there for the therapy sessions and for the drinks."
"I'm just excited for everyone to get to come back and enter the gates of Paradise. We had to take last year off which was a bummer, because I truly do love helping make the show, and I think America truly does love coming to the gates and walking down the steps with us," the 37-year-old told the outlet. "So I'm just happy that it's back."
Spade will reportedly act as the first guest host, with insiders telling Page Six that he was chosen because he is a Bachelor Nation superfan. The comedian has also "built a cult following among fellow fans because of the hilarious commentary" about the dating show on his social media.
Harrison’s departure was officially confirmed in June. Weeks earlier, he was criticized for asking for Bachelor contestant Rachael Kirkconnell to be given "grace" after a photo of the TV personality attending an Antebellum-themed formal surfaced while season 25 aired.
"I've had a truly incredible run as host of The Bachelor franchise and now I'm excited to start a new chapter," Harrison said in a statement at the time. "I'm so grateful to Bachelor Nation for all of the memories we've made together. While my two-decade journey is wrapping up, the friendships I've made will last a lifetime."
Bachelor in Paradise will premiere on Monday, August 16, at 8 p.m. ET on ABC.
