The incident conjured images of previous public exchanges, not least Affleck’s awkward dressing down by a frustrated Lopez for an apparent lack of enthusiasm while supporting her at the annual Grammy awards ceremony in February.

Analyzing their latest promotional appearance, body language expert Judi James claims Lopez conveys dominance, while Affleck’s posture suggests he is pleading with his wife during a moment of disagreement.

At odds: Jennifer Lopez and Ben Affleck conveyed moments of intense disagreement and ‘non-aligned thinking’ during their latest red carpet appearance, a body language claims

Here we go: The pair, who exchanged vows in Las Vegas last July, were seen gesticulating at one another on Wednesday evening

She told MailOnline: ‘This red carpet appearance was full of moments of contrasting body language moods from Ben and Jennifer. The photos do seem to suggest a moment of disagreement or non-aligned thinking.

‘Jennifer is upright, confident and commanding as she looks Ben in the eye, points and apparently directs with her index finger. We can’t see her face but there is no apparent rounding or fullness of her cheek to suggest she is performing a mouth smile here.’

She adds: ‘Ben’s response looks at odds with her state. He seems to have bent his knees to get his head level with hers and his close-quarters eye-contact suggests pleading or questioning.

‘His face looks rather drained and his mouth has fallen open, which can be a signal of disbelief. The stare has become more intense in the second photo and his brows are raised, again as though he is questioning her.

‘His lower teeth are showing now and he has adopted the pointed finger gesture, again as though he is questioning something she has said. She looks calm here.’

All’s well that ends well: James also suggested the couple’s subsequent red carpet kiss could be ‘ignored as a projected poses rather than a spontaneous, intimate moment’

Despite sharing a red carpet kiss in front of waiting cameras following the incident, James admitted the gesture could be construed as disingenuous.

‘Their posing rituals on the red carpet involved all the usual kisses and loving smiles, although these can always be ignored as projected poses rather than spontaneous, intimate moments,’ she explained.

However the appearance was ‘balanced’ by the couple’s more favorable off-camera interactions.

She said: ‘Where we could still see more authentic signs of love and affection between them that will hopefully balance these other poses came with their sweet hand-holding as they walked together.

‘There was one very dutiful moment when Ben adopted a security-guard pose, straight on to his wife and with his hands in the fig-leaf pose, while she turned her back on the camera to re-apply her lip gloss.

Awkward: Wednesday’s appearance comes after the couple hit headlines at the Grammys in February when Lopez was caught on camera demanding Affleck pretend to enjoy himself

Weighing in: Body expert Judi James has given MailOnline her expert opinion on the couple’s latest public appearance

‘Their smiles after this looked warm, knowing and grateful, providing some emotional balance.’

Wednesday’s appearance comes after the couple hit headlines at the Grammys in February when Lopez was caught on camera demanding Affleck pretend to enjoy himself in an embarrassing exchange, which he later discussed.

The couple’s exchange was transcribed by a lipreader, commissioned by DailyMail.com.

It came after Affleck was caught on camera angrily confronting Lopez at the January 18 premiere of her film, Shotgun Wedding.
