Rumor has it that Bachelor Pad -- the new Mike Fleiss late summer series that pits past Bachelor(ette) contestants against each other in a Survivor/Big Brother competition (with a little romance thrown in because hey, it's still The Bachelor) -- started filming today in Los Angeles.

Which Bachelor stars moved into the Pad to compete for cash? Two similar lists from sources outside ABC may reveal the identities of the 20 contestants:

"I'm pretty confident you will see most, if not all, of these people on the show," says Reality Steve, whose impressive track record in revealing accurate Bachelor spoilers leads us to believe his list (in parentheses: on whose season of The Bachelor(ette) they appeared):

Kiptyn Locke (Jillian)
Wes Hayden (Jillian)
Natalie Getz (Jason)
Dave Good (Jillian)
Jessie Sulidis (Jake)
Tenley Molzahn (Jake)
Nikki Kaapke (Jason)
John Hardesty (Jillian)
Juan Barbieri (Jillian)
Gia Allemand (Jake)
Mathue Johnson (Jillian)

Meanwhile, the celebrity blog Astro Chicks claim they have seen a list of Bachelor Pad contestants as well, and say that "if you put the two [lists] together, you will come close to the complete cast for this season of the Bachelor Pad." Here's their list (new names bolded), which notably includes three men from the current season of The Bachelorette:

Tenley Molzahn (Jake)
Valishia Salvage (Jake)
Elizabeth Kitt (Jake)
Gia Allemand (Jake)
Natalie Gertz (Jason)
Nikki Kaapke (Jason)
David Good (Jillian)
Kiptyn Locke (Jillian)
Wes Hayden (Jillian)
Mathue Johnson (Jillian)
Gwen Gioia (Aaron)
Craig McKinnon (Ali)
Jonathan Novak (Ali)
Justin "Rated-R" Rego (Ali)

Details on the format of the series are still "sketchy," according to Reality Steve, but he also reveals that the series will take place over "15 days of filming with two or three people getting voted off every other day," and that "Tenley and Kiptyn will be going on a date on this show."

Sad to see self-proclaimed princess Erica Rose (from Lorenzo's season) not on the list? Well, you clearly didn't notice her on last night's premiere of the new VH1 series You're Cut Off as one of nine rich girls who enter a rehabilitation program to stop being so spoiled and terrible. A much more fitting place on TV for her to be.

We made our own "dream cast" list for Bachelor Pad. See how it compares to the real thing:
