Lindsay's Boob -- The Gripping New Photo Shoot

Lindsay Lohan celebrated her newfound freedom with a death-defying photo shoot last week ... in the middle of an L.A. street ... replete with bloody knives and boob grabs.

It's her first photo shoot since the actress got out of house arrest two weeks ago -- taken in the middle of the night inside the famous 2nd Street tunnel in Downtown L.A.

If you're wondering who the dudes are ... it's Lindsay's photog BFF Tyler Shields and Virgin Mobile "Sparah"-half Spencer Falls ... who Lindsay was reportedly dating.

For the record -- Lindsay is NOT dating Spencer. But based on the pics, she's still a real handful.

'Sparah' RIPS Heidi & Spencer They're FAKE Celebs!

Virgin Mobile spoof couple "Sparah" just turned the tables on Spencer Pratt and Heidi Montag -- telling TMZ, feuding with Speidi is a GIANT waste of time ... because the former "Hills" stars are not even real celebs.

As we previously reported, Pratt went on the rampage recently -- calling "Sparah" a blatant rip-off ... and demanding Virgin Mobile pay him and Heidi money for bogarting Speidi's likeness in their new commercials.

But reps for "Sparah" -- the spoof celeb couple who stars in Virgin Mobile's new ad campaign -- tell us, Virgin's new duo has zero time to respond to Spencer's diatribe "due to their pressing endorsement commitments with Virgin Mobile and their frequent interactions with real celebrities."

Mirror mirror on the wall, who's the fakest of them all?

Spencer BLASTS Virgin Mobile -- 'Sparah' Is a Rip-Off!

Spencer Pratt is furious at Virgin Mobile -- telling TMZ, the cell company's new celeb couple spoof "Sparah" is blatantly copying Speidi ... and now he wants Virgin to start paying up for using his likeness.

If you haven't seen the commercials ... Virgin Mobile's new ad campaign is built entirely around a fake Hollywood couple called "Sparah" -- a mashup of the names Spencer and Sarah -- and Pratt is pissed he and Heidi have become the target of a national joke ... with no paycheck to show for it.

According to Spencer, Speidi's getting ripped off -- telling us, "They should being paying for using our likeness. It's obvious they are trying to be us."

Pratt doesn't stop there -- adding, he and Heidi "hate" Sparah ... "It's nuts how much [Virgin is] promoting them, when they are obviously copying us."

Attempts to reach Virgin's celeb couple were unsuccessful -- but we're guessing ... "Sparah has no comment."
