"There is a sadness," Patridge told People about her The Hills departure.
"[The show] gave me these opportunities, and the cast and the crew almost became like a family. But at this point all of us are ready to branch out, and I feel like all of us have changed and matured so much that we're ready to go out for the next big challenge."
Patridge's new reality project -- which is currently being shopped to different networks -- will "offer up a closer look at her Hollywood lifestyle," according to People, which added the series will also touch upon an upcoming role in the horror film Sorority Row and her Divine Rights of Denim clothing line.
In addition, Patridge also hinted the series might not take place in Los Angeles.
"It's also [about] how I stay grounded with my family," she told People.
Patridge said she also might have ditched her on-again/off-again boyfriend Justin Bobby for good.
"There's going to be new love, romances." she told People before adding there will be some closure between Bobby and herself during The Hills currently airing fifth season.
"It could resolve things in a good way or in a bad way. You'll have to see. But put it this way, I don't really hold back. I just let it all out this season. I fight back."
Patridge's deal with Burnett came less than a month after Lauren Conrad claimedThe Hills fifth season would be her last, and her departure was subsequently confirmed by executive producer Liz Gately.
However that doesn't mean The Hills fifth season will necesarily be its last, as Heidi Montag and Spencer Pratt have previously stated they plan on carrying the torch into a potential sixth installment.
"[They] want to continue The Hills forever!" Patridge told People about Montag and Pratt.
