Look away, Elmo! Katy Perry’s bringing her not-safe-for-“Sesame Street” plunging necklines to “How I Met Your Mother.”
In the next episode of the CBS comedy, the cleavage-baring “Teenage Dream” singer plays Zoey’s beautiful but not so bright cousin, Honey. For Barney and Ted, that means headaches and heartbreaks are on the way.
Perry’s “How I Met Your Mother” appearance airs Feb. 7 at 8 p.m. ET.
