Alcoholics Anonymous member Lindsay Lohan's 21st birthday Las Vegas party will be sponsored by a vodka company, according to her lawyer.

The actress' legal representative Mike Heller has revealed Svedka Vodka will be one of the sponsors of Lindsay's upcoming July birthday bash. "This should be one of the best parties ever," Heller said.

Free-flowing booze isn’t the only perk Lohan will enjoy. Svedka is only part of a sponsorship deal that could fetch the actress up to seven figures for her 21st birthday bash. Other sponsors include Las Vegas nightspots Pure nightclub, Caesars Palace and the Social House restaurant at Treasure Island, and the party is expected to take place in the city. The festivities will begin at Social House Restaurant at the Treasure Island and the party will move over to Pure nightclub.

However, the Lohan’s rep did not disclose her party plans, saying: "I am unaware of who is sponsoring Lindsay's birthday, as I am not the one planning it."

Lindsay checked into the Wonderland rehab centre in January, to be treated for alcoholism, following an all-night drinking binge at the Golden Globe Awards. She is now a member of Alcoholics Anonymous, despite not yet being legally old enough to drink in the US. Lindsay's mother Dina recently confirmed her daughter is still attending Alcoholics Anonymous meetings.
