Britney Spears celebrates birthday

Britney Spears celebrated her 28th birthday with a shopping spree in Los Angeles.

The pop princess made it her own prerogative to hit the shops in Hollywood with her agent Jason Trawick, who she is thought to be dating, before heading home to be with her sons, Sean Preston, three, and two-year-old Jayden James, reports People.

An onlooker told the mag: "Britney looked so happy - she seemed very excited to spend her morning with Jason."
