That time Ellen and Portia got into a hilarious prank war on Twitter...

When you're doing a vintage Jane Fonda workout in the comfort of your own home, the last thing you need is your sneaky spouse capturing the whole thing on video and then sharing it online with millions.

That's exactly what happened to Portia de Rossi, who was just minding her own business when Ellen Degeneres and her pesky smartphone caught the whole thing on tape.

But, that's not where the story ends. Oh no, it's not.

Portia got her revenge, catching Ellen singing Uptown Funk REALLY off-key while she pounded it out on the treadmill. (Warning: Bruno Mars, this may make your ears bleed.)

The entire prank war yielded some classically awkward footage and, more importantly, a glimpse into the lives of one of our favorite couples. All together now: Awwwwwwwww!
