The two have joint custody of their sons, Jayden James, 6-months, and Sean Preston, 18-months.

According to Wikipedia, she is best known for her studio albums, music videos, and songs such as "...Baby One More Time", "Oops!...I Did It Again", "I'm a Slave 4 U" and "Toxic".

In the early 2000s, Spears's success as a singer led her way to high-profile advertising deals and endorsements, as well as forays into other forms of media, including film and reality television.

Her third and fourth albums, Britney and In the Zone, were released during this era.
