I can almost hear Britney Spears saying it right now: “This How I Met Your Mother show is so fun, y’all. You should try acting on it too!”

In the next few weeks, the CBS comedy will be welcoming a few more of the music industry’s biggest names. First up, Carrie Underwood.

Although she sings about cheating men when she’s on the stage, Underwood’s pharmaceutical sales rep character is the one who may be stringing Ted (Josh Radnor) along. You can see more clips from that March 1 appearance - including Carrie dressed as a flight attendant and a cavewoman - after the jump.

After watching the videos, let us know what you think. Do you see a future in acting for the country superstar? While you’re thinking about that, check out this hot picture of Jennifer Lopez with Neil Patrick Harris below:

Why would J.Lo be seducing Barney Stinson? Well, maybe because Robin put her up to it? That’s right—Barney’s ex, still bothered by their break up, recruits Lopez (playing a self-help author named Anita) to turn the tables on the playboy.

To see if he gets walked all over by her Louboutins, tune in on March 8.
