The sexy and single Lindsay Lohan will once again be hitting the dating scene — for a good cause! The starlet, who split with DJ Samantha Ronson last year after a tumultuous relationship, will be auctioning off a Hollywood night out with the party queen herself to the highest bidder as she hosts the iRock4Haiti charity benefit at club Altitude 360 in London on February 16. The lucky fan will also receive first-class flights and a week in a swanky LA hotel. In another effort to help the victims of last month’s devastating earthquake in Haiti, for a limited time, Lindsay is donating 100% of the proceeds from her 6126 brand’s silver Fame leggings to the Save the Children Foundation. “It is truly horrible what has happened to the people and children in Haiti. I believe every company should do their part to help by donating what they can,” says the kindhearted actress.
