Has Lindsay Lohan Hit Rock Bottom?

If Britney Spears was able to make a comeback, can't Lindsay Lohan make one, too?

Not necessarily.

The difference between both celebs is that LiLo's never really had one definitive "low point" like Britney did in January 2008, when the pop princess was wheeled out of her home on a gurney and into an ambulance...

One might have argued that Lindsay Lohan's summer 2007 DUI arrests were her lowest point - Linds admitted that her life had "become completely unmanageable because [of] alcohol and drugs."

But now it's 2010 and Lindsay went to jail (and to treatment at UCLA) after violating her probation ... and she just recently failed a random drug test, testing positive for cocaine and last Friday went to jail yet again before posting bail at midnight.

It's hard to pinpoint Lindsay Lohan's lowest point in this whole mess! Does that mean it's still yet to come? Is there even such a thing as "rock bottom" for LiLo?

Of course, this hardly compares to Britney Spears getting placed on a "5150 hold," losing custody of her two boys and having to adhere to the rules of a conservatorship. But if an X17 source is correct, Lindsay could be headed in the direction of a conservatorship too if her new management team of Lou Taylor and Larry Rudolph (Brit's old team) have anything to do with it. Is Lindsay really Britney 2.0?
