Justin Timberlake might be a talented actor and singer, but his investing success has been more mixed. In 2010, Timberlake invested in the image-tagging app Stipple. Four years later, the company folded. Even worse, the entertainer was part of a consortium that bought the failing MySpace for $35 million in 2011, the equivalent of almost $50 million (£39.5m) in 2024. This turned out to be a big mistake and Timberlake reportedly sold his stake for just $1 to a fan in 2015.
He's since invested more successfully in businesses including audio company AfterMaster (of which he became co-owner) and fruit drink company Bai, which was acquired by Dr Pepper Snapple for $1.7 billion in 2016, the equivalent of $2.2 billion (£1.7bn) today.
