Spears often found herself in the spotlight less for her music than for events in her personal life, most notably her tumultuous marriage (2004–07) to dancer Kevin Federline. Her erratic behaviour during this time—at one point she shaved her head and was briefly hospitalized—resulted in her being placed under a court-ordered conservatorship (also known as guardianship) in 2008; her father was named as a conservator. Concerns about this legal arrangement later caused fans to start the online campaign #FreeBritney.
