CBS announced this afternoon that Katy Perry will make a special guest appearance on How I Met Your Mother later this season, in an episode entitled "Oh, Honey". She will reportedly play Zoey's ( Jennifer Morrison ) cousin, a beautiful, naive girl who the gang resorts to calling "Honey". Katy Perry Brings the Honey Katy Perry has made a lot of guest appearances on television shows ( Sesame Street , Saturday Night Live , American Idol , and so on). However, none of these roles have ever been challenging enough to test whether or not her acting abilities are as good as her musical talents. This, I believe, will help to settle that question. The one thing that I can say ahead of time is that I guarantee she'll be better than Britney Spears was when she showed up on HIMYM , which I'll admit is not saying a lot. Anyway, I look forward to seeing Katy Perry on How I Met Your Mother . It should be a fun episode to watch.
