The first photo of Katy Perry on the set of How I Met Your Mother has hit the web.

Perry will play “Honey,” on the Feb. 7 episode of the CBS sitcom. She’ll force Neil Patrick Harris‘ character, Barney, to get emotional when opening up about his womanizing ways, Access Hollywood reports.

It’s the second time in recent months she worked with Harris; they also co-star in the live action Smurfs, due in theaters Aug. 3, 2011.
