Those who bought their Lollapalooza 2010 tickets on Tuesday did not make their purchases completely blindly--even though the official lineup won't be announced until April 6.

Rumored headliners have been floating around for a few weeks now, and with the big announcement around the corner, people are taking the risk and buying tickets based on those rumors.

Three-day passes for the annual music festival held in Grant Park were available at 10 a.m. Tuesday for $190 at the event's website. When they sell out, the remaining ones will be priced at $215.

The festival will be in Grant Park August 6 through 8.
