Lindsay Lohan loves her water-disguised vodka, and now a vodka company, Svedka vodka, will sponsor her 21st birthday in Vegas on July 2nd. Lohan completed revolving door rehab early this February, and was seen out partying the week of her release. There’s little doubt that she’s drinking again, and it seems just like her to give a big finger to world and have a vodka company bankroll her birthday. She was seen swigging straight from a vodka bottle recently, so she seems to have given up the convention of hiding the stuff in water bottles anyway:

Alcoholics Anonymous member Lindsay Lohan has lined up Svedka vodka to sponsor her 21st birthday blowout in Las Vegas, a rep for the brand confirmed to us yesterday.

It’s part of a deal that could net the star up to seven figures for the July 2-3 celebration. That’s even before the Wonderland rehab center she attended gives her a refund.

Other partners include Pure nightclub, Caesars Palace (which is providing a “specially designed” suite) and the Social House restaurant at Treasure Island.

In the pay-to-play world of celebrity events, Vegas nightclubs alone have been known to offer up to $400,000 to land a top name.

Meanwhile Britney’s cad lover Calum Best is back in England, and The Sun points out that he was seen leaving a party with Miss World Mary Stavin. Normally I would point out that the picture shows Calum in the front of the car, and the woman in the back, but since it’s him and there are so many stories of him blatantly hitting on women in Lindsay’s presence – including staff at the hotel where they were saying – it’s probably true that he hit the sheets with her afterwards.

For Lindsay’s part, she was seen cozying up to an unattractive guy at dinner. Guess that on-off relationship with Calum is forgotten until the next drunken get-together and public row. Lohan is wearing a ring on her left ring finger, but that’s probably just for attention.
