U2's Bono is making millions through the social network site Facebook, it has been reported.

The frontman, who owns 1.5 percent of Mark Zuckerberg's Facebook, is set to make a small fortune from the site.

Bono's own provite equity firm Elevation Partners has quadrupled its initial investment in the site to 750 million dollars (485.3 million pounds), due to the success of Facebook, reports Word.

The Social Network, a film about Facebook founder Zuckerberg, was released in October.

Meanwhile, U2's Bono and The Edge will be attending all the upcoming preview performances of the Spider-Man musical following troubles with the production.
