Britney Spears Rehearses for Mother
04/29/2008 AT 12:00 AM EDT
Spears headed out around 8:30 am and made a quick stop at Starbucks in Beverly Hills before arriving at Fox.
Spears first appeared on the show in late March playing a receptionist named Abby and will return to the role in an episode titled "Everything Must Go" airing May 12. In the episode, Spears and Barney (Neil Patrick Harris's character) taunt Ted, played by Josh Radnor, by pretending they're in a relationship. Barney, who is desperate for a response from Abby pops her a shocking question.
The singer's first spot on the show earned her positive reviews and brought in the show's highest ratings yet. -- Jessica HerndonMonty Brinton/CBS
