2008
On the evening of January 3, 2008, after not sleeping for over four days, Spears refused to relinquish custody of her children to Federline's representatives. In response, police were called to Spears's home. She was hospitalized at Cedars-Sinai Medical Center after she "appeared to be under the influence of an unknown substance", though blood tests tested negative for any illicit substances. She was held for psychiatric evaluation for two days. Pending a February 19 hearing, Commissioner Scott Gordon issued an order on January 14 stating that her visitation rights have been suspended indefinitely. On January 31, a court placed Spears under temporary co-conservatorship of her father James Spears and attorney Andrew Wallete, giving them complete control of her assets. As a result of an order placed by her psychiatrist, she was taken to UCLA Medical Center to be put on a 5150 involuntary psychiatric hold for the second time that month. On February 1, a restraining order was issued against Sam Lutfi, a prominent figure in Spears's life. She was released from the hospital on February 6, amid speculation that she has bipolar disorder, although medical records are classified, and no confirmation has been made. Her parents expressed disappointment and concern at the decision to release her. She has regained some visitation rights after coming to an agreement with Federline and his counsel. On July 18, 2008, Spears and ex-husband Federline reached a custody settlement in which Federline retains sole custody while Spears keeps her visitation rights.
In 2008, Spears guest-starred on CBS's television show How I Met Your Mother playing a receptionist. She received positive reviews for her performance as well as bringing in the series highest ratings ever. Spears reprised her role in May 2008, leaving the storyline open for a future return.
On June 11, 2008, Jive Records announced that no further singles would be released from Britney's fifth studio album Blackout since Spears is working on a new album. J.R. Rotem, Keri Hilson, Sean Garrett, Guy Sigsworth, Nate "Danja" Hills, Bloodshy & Avant and Rodney "Darkchild" Jerkins have all been confirmed to be working with Spears on her sixth studio album, yet untitled.
On September 7, Spears opened the 2008 MTV Video Music Awards for the third time. Although having not performed, a skit with Jonah Hill was pre-taped, as well as an introduction speech to the official opening of the show. Spears won Best Female Video, Best Pop Video and Video Of The Year for "Piece of Me".
On September 11, Popjustice revealed that the upcoming album will be released in December, with the first single out in November.
