Last night, the paparazzi and their tech blogging equivalent gathered at Pravda, a once trendy Soho hot spot, to celebrate apps with fly girl jail bird Lindsay Lohan.

The upside for Lohan in accepting this role as a human tiger/selfie prop is clear: her younger brother Michael Lohan is an "owner" of the karaoke app Just Sing It and she's up for an equity stake "should Lindsay's marketing efforts prove successful."

The benefit for Just Sing It is hazier. Among U.S. consumers, the app, which has funding from Lerer Ventures, is currently at no. 268 in the Music category of the iOS store—down almost 100 spots since we wrote about the party last week.

While Lilo's fur-clad appearance got the app coverage in places like Just Jared, TMZ's report didn't even mention the name of the startup, only that "no one got their face punched in."
