The duo hid -- and cuddled -- inside of a women's bathroom in order to surprise, shock and bring excitement to some folks who just wanted to use the restroom. As Ellen explained, the women who got to experience this surprise were "either lucky or unfortunate."
Watch the video to see some incredible reactions. There's the "Cover-your-mouth-because-you-just-caught-JB-and-Ellen-cuddling" look. Then there's the "scream-so-loud-you-make-Biebs-cover-his ears" reaction look, which is priceless. Oh, and there's also the old "hi-Justin-can-i-have-a-hug" response, of course.
Overall, we really can't blame these women for their excitement and shock. I mean, how would you react if you walked in on Bieber signing "Baby" in a bathroom stall as Ellen played with a doll?
