Most of the Paradise cast had already been announced late last month, around the time ABC disclosed the new season will premiere with a two-hour episode on Tuesday, August 7 at 8PM ET/PT.
Beginning the following week, Bachelor in Paradise will air on Monday and Tuesday nights from 8-10PM ET/PT.
Wills was eliminated during the latest episode of The Bachelorette after he traveled to the Bahamas with Becca.
The self-proclaimed nerd became vulnerable with Becca and opened up to her, revealing he was falling in love with her more and more every day. He was hoping to end up with a marriage just like his parents' relationship, which is one to admire.
But Becca wasn't on the same page, and so she made her "toughest decision yet" to send Wills home before his family got involved.
Wills didn't see his ouster coming at all, and he admitted he was absolutely "devastated" and "heartbroken."
"I'm absolutely wrecked right now. I thought she was going to pick me. That's why this is shell-shocking. I couldn't do anything more than I did. I thought she cared about me the way I cared about her. I wasn't ready to go home, not like this," Wills said in his final words on Monday night's episode.

"I'm absolutely heart broken. You have someone get in your heart, and then you have them say, 'No thanks,' which is what she did. The hardest part was her saying, 'I know you will find your person.' That's probably the worst thing that she said, because that means she's not my person."
