Jennifer Lopez was caught in a fiery exchange as she yelled "f*** you, bye" while leaving her gym, in what has been described as a "flash of irritation".
The 53-year-old seemed to be frustrated with the waiting paparazzi and yelled at them before driving off in a waiting SUV. A body language expert has suggested it shows Jennifer's "often sweeter mood is eroding".
Speaking exclusively to The Mirror, Judi James suggested J-Lo is "mirroring" her husband with he outburst following his recent tense exchange with paparazzi.
"Jennifer always seems to understand the importance of adopting the right pose for the press and keeping that A-list brand thriving but it's pretty obvious from her verbal sign-off here that the relationship with the paparazzi might be wearing a little thin right now.

She could be 'mirroring' Ben Affleck (Jen Lowery / SplashNews.com)"Husband Ben always seems to have a short fuse when it comes to posing up or being snapped, even at red carpet events, where he can look barely able to go through the motions of fake smiling without looking impatient or uncomfortable, and it's possible that Jennifer's sudden flash of irritation might be something she is mirroring from him and that her often sweeter mood is eroding, which would be a pity," Judi said.

Jennifer's workout session got off to a rocky start as she appeared to be locked out of her luxury fitness studio. The singer was seen knocking on the door of the Tracy Anderson Method Studio after failing to get in.
She decided to lean against the wall until she was finally let inside the building.

However, she added: "Her stunning gym wear doesn't look like a low-profile option.
"Caught waiting for the door to open she bends one knee to adopt a very elegant leg pose, suggesting she still finds it hard to not be on-brand. Her other movements suggest understandable impatience though as it's not every day a star of her status gets left taking it out on the door knocker."
The body language expert suggested a comment from a photographer could have sparked Jennifer's swearing.
Judi said: "Ben has been seen to communicate with the paparazzi but his style is often sarcastic rather than verbally angry so it could be that Jennifer has raised the bar with this small outburst."
