An air of discontent was palpable as Jennifer Lopez and Ben Affleck made their grand entrance to the LACMA Gala in Los Angeles.

Stepping onto the red carpet, they joined other A-list celebrities like Kim Kardashian and Paris Hilton.

However, it appeared that even rubbing elbows with these stars wouldn't take away from the fact that it seemed clear that Affleck was not pleased to be there.

Judi James, a body language expert, was quick to comment on the lack of a smile from the "Gone Girl" actor in stark contrast to the "Jenny From The Block" singer.

To complement JLo's semi-sheer gold gown with its lace skirt detailing, she chose nude platform heels and a ruby necklace that demanded attention.

Further accessorizing included teardrop gold earrings and a matching bracelet alongside a stylish gold clutch bag.

At the event, Ben's ultra-dapper look was unmistakable. He sported an impressive tuxedo with a pristine white shirt and finished his ensemble with a bow tie.

Speaking with The Mirror, Judi noticed that he seemed to be having a positive impact on his wife, who appeared more "serious" than she generally does.

Despite being one of Hollywood's brightest and having tied the knot with music royalty, Ben Affleck's body language at public appearances and red carpets appears to tell a different story.

His gestures give off an aura of complexity, suggesting he is not entirely comfortable in the spotlight. An expert in the field of body language made this observation.

Carrying on, Judi observed: "Ben seemed to be going through the motions here, and even Jen - usually so convincing - appeared a bit solemn. His stance was wide-legged with his chest puffed out, eyes distant as though he'd much rather be doing anything other than posing for pictures."

Judi quickly observed an exciting change in behavior from Ben; he had begun to break into a half-smile when glancing at Jennifer. Her assessment of the expression was that it appeared more akin to a forced act than an authentic display of joy.

The "Hustlers" actress was with Ben, and it was clear that something had changed. Her dress featured a split skirt that allowed her to show off a bit of leg; however, this wasn't her typically passionate attitude towards him. Ben has been known to have an impatient nature when it comes to the press, and this could be an indication that Jennifer is now picking up on his mood.
