The 'Hold It Against Me' singer gave away some of her secrets in Us Weekly's feature entitled 25 Things You Don't Know About Me.
For secret 19, Spears said: "I don't own a cell phone", while unknown fact 9 was: "I have more than 50 purses in my closet."
She also admitted that her "favourite ice cream is orange sherbet", she loves "chewing ice" and she takes "two baths" a day.
The 29-year-old, who is preparing to release her new album Femme Fatale, added: "I can eat chocolate morning, noon and night . I make a mean fake dinosaur when playing with the two loves of my life, Sean, 5, and Jayden, 4."
Spears also confessed that it was her who "made the first move" on her boyfriend Jason Trawick, who she began dating in March 2009.
