We were on scene right after the crash, where Jeff told us he was "a little shaken up" -- then immediately cracked a joke at a fellow roaster, saying, "That's what happens when you don't feed Lisa Lampanelli!"

Now for the amazing part -- even though Jeff's Prius took a major hit in the accident ... he still managed to drive off in it.

Kaley -- who also posed for "Maxim" -- is laid up in an L.A. hospital and won't be able to tape her show tomorrow night. The show, by the way, is a huge hit for CBS -- anchoring its fall lineup on Thursdays at 8 PM.

A law enforcement source tells TMZ ... based on the preliminary investigation ... it appears Tom Brady was not at fault -- that he had the green light.

Rikki -- who starred on the show "A Double Shot at Love" with her sister Vikki -- experienced some dangerous swelling in her brain due to the injuries she sustained from the crash ... so doctors decided to remove 2 sections of her skull.

According to Vikki, Rikki's skull was reassembled on June 24 -- her last surgery to date -- a couple weeks after we caught the twins out in L.A. ... where Rikki modeled her brain-protecting helmet (see video).

Rikki's head is back in one piece -- but her sis adds, "Rikki still has trouble with fine motor skills in her left hand and some of her facial expressions. She also has frontal lobe syndrome which messes up her memory."

TMZ spoke to the Hulkster -- who's currently hospitalized in Clearwater, FL -- and dude tells us he was picking up seashells this weekend with his girlfriend Jennifer ... and the constant bending over eventually got the better of him.

Hulk -- who's had multiple back surgeries in the past -- says he must have aggravated his old injuries ... because the next morning he could "barely move" and had to call an ambulance.

Cops have confirmed ... "The equipment pertaining to the stunt was impounded by the Indiana State Police."

We've learned the person who called 911 from Gabor's house mentioned flu-like symptoms and body pain.

We're told a private ambulance has taken Gabor to the hospital, without emergency lights flashing ... an indication her life is not in immediate danger.

UPDATE: Zsa Zsa's publicist, John Blanchette, tells TMZ the doctors have stabilized Gabor's condition -- though she's still undergoing certain tests."
