Looks like Whitney Port bolted from The Hills just in time.

Now the star of her own Hills spinoff The City, Port says she's truly taken aback by her former show's new season -- which spotlights Heidi Pratt's drastic plastic surgery, her husband Spencer Pratt's serious rage issues and Kristin Cavallari's drug problems.

During her time on The Hills, Port was Lauren Conrad's right-hand pal at Teen Vogue and the L.A. office of PR company People's Revolution before heading to NYC to shoot The City two years ago.

"I feel like they're all self-imploding or something," Port, 25, said of her former castmates during a Friday interview for On Air with Ryan Seacrest on KIIS-FM.

"I'm just in shock," she added, without naming any names. "I think they're just going crazy."

The star -- perhaps familiar with Spencer Pratt's rants against Audrina Patridge, Brody Jenner, sister-in-law Holly Montag and other perceived enemies -- feared getting too specific.

"I don't want to say so much because I feel like they're going to attack me," she told Ryan Seacrest.

In the latest issue of Us Weekly, a source says that Spencer has "brainwashed" his wife Heidi, and that the isolated couple have spent $400,000 on supposedly mystical crystals.  As for Spencer's combustible behavior? "[Heidi] loves its," another insider says.  "She loves this persona that Spencer has become. She's just as delusional as he is."
