The former Liverpool skipper was jokingly targeted by the Red Devils faithful during the half-time analysis of their 4-1 win over Chelsea on Thursday night.
As Sky returned from a commercial break, fans could be heard singing: "Jamie Redknapp is a w*****, is a w*****."
It was all in good jest, with the ex-Reds midfielder seen chuckling on the sidelines.
And his colleagues also failed in trying to hide their laughter, as host Kelly Cates grinned as she delivered a piece to camera.
Chelsea cult hero Jimmy Floyd-Hasselbaink could also be seen laughing, while United Women's goalkeeper Mary Earps also cracked out a smile.

Redknapp looked to get his own back to United's fans after the match as he commented on Casemiro's no-look pass to help set up Anthony Martial's goal.
He referred to it as a 'Robert Firmino pass' in reference to the Liverpool forward, which led Cates to say: "They won't like that here."
Responding, Redknapp said: "I don't care, I've taken enough stick tonight."
