This may become one crowded kitchen.
Heidi Montag, Jake Pavelka, Danielle Staub and other reality alumni are all going into the food business together for an upcoming series that places some big personalities under heavy pressure, PEOPLE has learned.
"They are revamping a restaurant from the ground up," says a source on the set of the new reality series, slated to air on VH1. "They started shooting this past weekend."
On the show, the cast will be tasked with opening a restaurant in just 28 days.
The stars, who filmed Tuesday at Café Med in West Hollywood, have remained tight-lipped, with Staub announcing on Twitter: "I'm working on a project. Let you know soon what and with whom!! Xxoo."
Pavelka also tweeted Tuesday, "Crazy fun day of shooting!"
