U2 frontman Bono is hoping to cash in on Facebook by almost doubling his stake in the social networking site.
The singer's private investment company, Elevation Partners, already owns $80 million in shares in the company, but has now upped its stake to a whopping $140 million.
He's hoping that the investment will turn around a series of terrible financial decisions made in recent years.
His California-based company lost millions after a vast investment in smart phone company Palm tanked when its shares plummeted, earning itself the title of 'Worst Investor' by one financial journal.
24/7 Wall Street called Elevation Partners "arguably the worst-run institutional fund of any size in the United States," adding that it had made "an unprecedented string of disastrous investments which even bad luck could not explain".
