Peloton's new holiday ad went viral after many considered it sexist and offensive, as it shows a husband giving his wife the expensive exercise bike for Christmas. In response to the controversial ad, NFL Network's Jane Slater tweeted that she was not offended when her ex-boyfriend gifted her a FitBit — until it revealed he was cheating on her.

"An Ex Boyfriend once got me a Fitbit for Christmas," Slater tweeted. "I loved it. We synched up, motivated each other ... didn’t hate it until he was unaccounted for at 4am and his physical activity levels were spiking on the app."

She continued: "Wish the story wasn’t real."

The NFL reporter made sure to clarify that her former partner was not getting an early-morning workout at the gym: "Spoiler alert: He was not enrolled in an Orange Theory class at 4am."

Slater's tweet as of Sunday morning had been liked more than 470,000 times and retweeted 45,000 times.
