Britney Spears began recording tracks for Blackout in August 2006, while she was seven months pregnant with Jayden James. Recording continued at Spears’ house in Los Angeles, three weeks after she gave birth. Keri Hilson commented that "She gave 150 percent. I don’t know any other mother that would do that."
Danja added that despite all her problems in her personal life, "As far as her work ethic, I haven’t seen anybody come in like that and do what you go to do.”
Although Spears arrived late to the recording sessions, she caught them off guard with her efficiency and professionalism, with Lewis adding, "It was absolutely nuts, and she took directions very well. I don’t know what I was expecting because we went in to cut that record the day after she filed divorce from Kevin."
T-Pain, who co-wrote “Hot as Ice”, was in the studio with Spears in February 2007, and stated that one of the three songs they recorded was finished in only an hour. He said that he "thought she was going to be sitting on the couch eating Doritos or nachos or something, but she came in, shook my hand, gave me a hug and went right in the booth. She got in there and put it down."
