According to Max George's standards, Lindsay Lohan is apparently a "good girl," but if he has it his way, she's going to be getting a whole lot WORSE before these two are through together!

It appears that his influence is ALREADY re-igniting some of her old bad habits…like her penchant for five-finger discounts!

As we've reported, the hard-pAArtying, problem-prone starlet spent her week as a groupie for her latest love interest's band, The Wanted, as they drove up and down the East Coast for various performances!

And according to George at Z100's Jingle Ball 2012 presented at Madison Square Garden Friday, he openly admitted that LiLo was definitely not using him as a sober coach during their time together!

He explains:

“She can party, like, nearly as hard as we can! We had a big night on The Box [in New York City] where Ed Sheeran came on with us and a few of our mates as well. We just had one big party, it was great. I’m sure she’s got people around her that know her much better than we do who can do that [handle her hard pAArtying]. We’re probably not the best influence, to be honest. I suppose we’re all good mates already, so I hope that lasts.”

Oh BOY!

And given Lindsay's latest Twitter activity, we're pretty sure that she thinks that she and the boy-bander are MORE than just good mates, as she posted a picture last night of a sweatshirt she apparently swiped off of him before he took back off for England!

The message read:

Hey! If that's all she managed to slither off with, then by our standards, he's doing all right!

LOLz!

We kid, we kid!

But we'd tread lightly if we were him!

We've all seen LiLo go from fun to DRAMA and SCARY in 13 seconds flat, and wouldn't want to see his gorgeous face become some of her collateral damage!
