8 Celebs Betting Big on Startups

More than just Oscars and Grammys, becoming a big star today requires mastering the world of online and social media. So it's no surprise that many of today's brightest glitterati are also eager to become leading digerati, investing in a wide range of startup tech companies. Mashable presents eight stars making a splash with their online investments:

• Lady Gaga. Along with Kanye West, Gaga contributed to the $7.5 million financing raised in July by Turntable.fm, a music rating and deejaying site.

• Leonardo DiCaprio. He contributed to the $4 million first-round funding into Mobli, a social media company that specializes in sharing user videos.
• Justin Timberlake. He's a co-owner of MySpace and now he's invested in Dekko, a stealthy new startup that apparently is trying to create an "augmented reality" experience, bringing online information to real-world experiences.
• Ashton Kutcher. The Two and a Half Men has invested in more than 10 companies now, including Foursquare, GroupMe, and TinyChat. (Just don't ask him about Twitter). (Actually, maybe he should be careful about all those startups, too).
