Lindsay Lohan is once again partying all night and shopping every day, which seemed inevitable once she got out of rehab, and she’s using the same old tired methods to conceal and cope with her addictions. She’s been seen out more than once toting her own personal water bottle. And someone claims they saw as assistant fill her bottle with vodka, just like she used to do before she went to rehab three times:

Lindsay raised more than a few eyebrows when she arrived at new Hollywood club Goa carrying a suspicious water bottle on December 8. “Lindsay didn’t order anything to drink but kept sipping from her bottle,” an eyewitness at the club reveals…

Another eyewitness saw the star in November at Stereo in NYC, where an assistant filled a water bottle with Grey Goose vodka.

Last week there was a story that Lohan got wasted at a party near her hometown in Long Island with her then-boyfriend, Riley Giles. The guy was said to have cheated on her by screwing another party-goer that night out in the woods, but it sounds like she was drunk by then anyway. She refused multiple offers of rides and ended up having Riley, who was also in no state to drive, take her home.

And Star Magazine has a story this week that Lohan is looking for a wealthy guy to support her trashy couture lifestyle, which could explain her brief hookup with Stavros that was quickly thwarted by jealous Paris. We reported back in September that she was begging even casual acquaintances for $10,000, and now she hopes to get a more permanent source of cash since her failing career isn’t allowing her to buy the meaningless accoutrements of extreme wealth that she’s accustomed to:

“She’s dying for some rich guy to take care of her!” [a] friend reveals to Star.

She thought she’d found one in superwealthy shipping heir Stavros Niarchos, who wined and diner her all over LA in late November. But he shocked her earlier this month by jetting off to Miami and meeting up with old love Paris Hilton.

“Lindsay says Stav’s money makes him hot,” says the pal. “She loves to talk about how he’s ‘richer than God.’”

But Stavros, 22, isn’t the only guy Lindsay’s hitting up for money. She asked ex Calum Best, the 26-year-old British millionaire playboy, for money. And she even called rapper 50 Cent, who’s helping with her upcoming album, and requested $20,000 in early December.

Thankfully Star reports that 50 Cent refused to give Lindsay any cash. She’s said to be hard up for money since she only received a paltry $800,000 for the film Dare to Love Me. That sounds like a lot of money but it’s not enough to keep up with her lavish spending.

On Friday Lohan called into a Las Vegas radio station that was holding a contest for Hannah Montana tickets for anyone who could get a celebrity to phone in. She told the DJs that she’s “growing up” and that her “life is different now” and that she’s a “different person.” She supposedly wanted the Hannah Montana tickets for a friend’s nieces, but since she’s so hard up for cash I wouldn’t put it past her to scalp them. You could get an astronomically priced giant purse for that money that will be in style until at least the end of next season.

Lohan is shown out shopping on Saturday, thanks to WENN and Splash News. She is looking really beat lately.
