The duo finished the script, initially titled Star Beast it was changed to Alien after O'Bannon noticed the number of times the word "alien" occurred in the script. Their script was sold to Brandywine Productions, which had a distribution deal with 20th Century Fox.

For Blackout, Spears worked with them on "Radar", "Freakshow" and "Toy Soldier". When the album was considered to be finished, Bloodshy & Avant were persuaded by her A&R Teresa LaBarbera Whites to work on a new track. Winnberg commented that it had always been an unwritten rule not to write songs about Spears's personal life since the label rejected "Sweet Dreams My LA Ex", a response track to Justin Timberlake's "Cry Me a River". However, the duo wrote "Piece of Me" with Ahlund and sent it to Spears, who loved it. Bloodshy & Avant worked on the track at Bloodshy & Avant Studios in Stockholm, Sweden, and Spears recorded her vocals at Chalice Recording Studios in Los Angeles, California. Winnberg stated that Spears was extremely psyched when she came to the studio, where she recorded the song in about half an hour as she had learned the lyrics by heart in her car.
