It looks like the guests on Ellen DeGeneres's show aren't the only people she pranks! Over the weekend, Ellen tweeted a video of her wife, Portia de Rossi, doing one of Jane Fonda's workout tapes. Ellen explained that Portia told her she could watch her exercise, adding, "She didn't say anything about filming and tweeting it." In the video, Portia calls out, "This is hard!" And by the end, she realizes that Ellen's been filming her the whole time.
The pranking didn't stop there, though, because Portia decided to get back at Ellen by filming her running — and belting out a song — on the treadmill!
