Portia de Rossi and Ellen DeGeneres seem like they’re always having fun together, so it’s no surprise that Ellen–who is known on her talk show for her cheeky sense of humor–decided to have a laugh at her wife’s expense recently during a workout.

When Portia popped on a Jane Fonda workout and began moving along to it, Ellen filmed it and posted it to Twitter, sharing it with her 37 million followers. What Ellen wasn’t counting on, however, was retaliation, and when Portia filmed her singing loudly along to Mark Ronson’s “Uptown Funk” while running on the treadmill, she shared it on her own Twitter account as revenge.

Ellen initiated the old-school workout viewing because she wanted to be more knowledgeable about them for their re-release on DVD this week, and she says she took out her phone as soon as she saw Portia take an interest in them.

“I’m sitting there, and it’s Saturday afternoon, and Portia’s sitting doing a jigsaw puzzle, and I said, ‘I’m going to pop [the Jane Fonda workout video] in. I want to see this because I want to be able to talk about it.’ So she got up from the jigsaw puzzle she was doing, and I took the phone out, and started recording her,” DeGeneres said.

.@PortiadeRossi said I could watch her do her @JaneFonda workout. She didn't say anything about filming & tweeting it http://t.co/9d30nps3pN

The couple endured several rounds of rumors last year regarding their relationship after word began spreading on the web that Portia resented Ellen’s close friendship with actress Sofia Vergara. Talk of divorce was even brought up, but the couple denied that anything was wrong and continued to share photos and social media updates showing them having fun together.
