LiLo’s interest in app more than musical

Lindsay Lohan isn’t just singing it, she’s selling it.

The fallen starlet could be looking to the tech world for a comeback — as she has started promoting a new karaoke app, Just Sing It.

But Lohan is more than a fan of the app — which she tweeted about recently. She and her brother, Michael Lohan Jr., stand to earn an ownership stake in the company should Lindsay’s marketing efforts prove successful.

The exact size of the equity stake was not disclosed.

Michael, 25, introduced his big sis to the app and has been working with its founder, Alec Andronikov, for nearly a year to launch Just Sing It, which has been billed as a musical, “Draw Something.”

LiLo has become the app’s most famous fan, but until now it hasn’t been known that she and her brother stand to gain financially if Just Sing It succeeds.

“People must be asking, ‘Why is she playing [the app], why is she endorsing this product?’” Michael told The Post. “She knows I am an owner and was a lot more willing to participate in a heartfelt way.”

New York City-based Just Sing It recently raised $1 million from venture-capital firms, including Tribeca Venture Partners and Lerer Ventures.

The app has been downloaded 100,000 times and a million songs have been shared since launching less than a month ago, Michael Lohan said.

LiLo, on top of acting, dabbled in pop stardom earlier in her career, and she has said she is working on a new CD. Her next stint, however, is in court-mandated rehab set to begin May 2 for 90 days.
