The singer, who is believed to have been dating agent Jason Trawick for about a year, was spotted being taken to a drive-through in Los Angeles on Sunday afternoon.
Spears was reported to have dumped Trawick in January over rumours that he had flirted with other women as he spent time at LA's Roger Room bar.
At the time, a friend of the star said: "This isn't the first time Britney has been let down by the man in her life. LA is a small town for those in the know and Jason's antics didn't take long to filter through to her."
Spears has two children with ex-husband Kevin Federline.
