Ellen DeGeneres and wife Portia de Rossi are in the midst of a hilarious video prank war after the comedienne posted a video of her wife busting out some aerobics moves.

The talk show host filmed her wife of six years doing a Jane Fonda workout video at their home and posted it online.

"Portia said it was okay if I watched her do her Jane Fonda workout. She didn't say anything about filming it and putting it on Facebook," she wrote alongside the video.

Portia didn't seem all too impressed at the end of the video when she realised the 56-year-old was filming - however she then retaliated with a video of her own!

The 41-year-old Aussie actress got her wife back by secretly filming her running on the treadmill and belting out “Uptown Funk” by Mark Ronson.

"I got you back @theellenshow! Don't believe me? Just watch," she tweeted.

Ellen responded by tweeting: "You're pretty brave for someone who likes to do naked pilates."

It's war!
