Jennifer Lopez has signed on for a guest starring role in an upcoming episode of CBS’ “How I Met Your Mother.”

The actress/singer/designer will play Anita Appleby, “a no-nonsense author of self-help books that teach women how to mold the perfect man through the power of denial.” Anita makes it her mission to “break” Barney but it appears she may have met her match.

“We couldn’t be more excited about Jennifer Lopez joining us on ‘How I Met Your Mother,’” said series executive producer and co-creator Carter Bays. “We’re looking forward to a week of revealing outfits and sexy dance moves the likes of which this show hasn’t seen since Regis Philbin guest starred.”

The episode is scheduled to air in March.

J.Lo won’t be the only diva appearing on HIMYM in March though. Carrie Underwood recently taped her own guest spot, which will air on March 1.

CBS also announced this week that the series was picked up for a sixth season.

Meanwhile, Jennifer Lopez is rumored to have a cameo as a lunch lady on an upcoming episode of “Glee” too.  Guess she really is still just “Jenny from the block”!
