The romance reality show features 19 former Bachelor and Bachelorette contestants looking for a second chance at love and a cash prize.
Speaking to ET Online, the show's host Chris Harrison confirmed that Pavelka - who split from fiancee Vienna Girardi this week - will "play his part" in the series.
"Now that the news is out about Jake and Vienna I can also announce that Jake will be coming on and be a part of Bachelor Pad," he said. "I can't explain everything. It just kind of happened, but Jake will definitely play his part now in Bachelor Pad."
Pavelka previously appeared on Jillian Harris's season of The Bachelorette, before fronting the 14th instalment of The Bachelor where he met and proposed to Girardi.
Bachelor Pad premieres August 9 on ABC.
