Britney celebrates Mother's Day with CBS and her old friends at "How I Met Your Mother."

Singer Britney Spears will be guest staring in another episode of "How I Met Your Mother."

The broadcast date is Monday, May 12 (8:30-9:00 PM, ET) on the CBS Television Network and the network will surely have a May sweeps hit on their hands. The day after Mother's Day episode will surely top her previous engagement.

When Barney and Abby realize that they have one thing in common - their mutual hatred of Ted - the "couple" decides to go to the bar to flaunt their new relationship in Ted's face. Desperate to get a rise out of his former pal, Barney pops a surprising question to Abby.
