Jake Pavelka, Heidi Montag and Danielle Staub are reportedly going to be starring in a new VH1 reality series together.

The former The Bachelor, The Hills, and The Real Housewives of New Jersey stars have begun filming a reality series that will follow the trio and several other reality stars as they attempt to go into the food business and open a restaurant in only four weeks, People reported Tuesday.

"They are revamping a restaurant from the ground up," a source told People. "They started shooting this past weekend."

Pavelka, Montag and Staub were spotted filming their new show on Tuesday at West Hollywood's Cafe Med, however they remain hesitant to disclose any details.

"I'm working on a project. Let you know soon what and with whom!! Xxoo," Staub wrote on her Twitter account.

"Crazy fun day of shooting," Pavelka also tweeted Tuesday.
