Roxanne Pallet has become the most talked about housemate of this Celebrity Big Brother series, thanks to her allegations last Thursday night that Ryan Thomas had punched her in the ribs in a "deliberate and unprovoked attack".

But when footage from the so-called attack was shown to viewers, it appeared Roxanne had hugely exaggerated what had happened - and decided to quit the CBB house 48 hours later after she was booed on Friday night's live eviction episode.

Now the ex-Emmerdale star has broken her silence to "massively apologise" for her actions and admitted she "got it wrong" in an emotionally charged Jeremy Vine Show appearance.

Roxanne's body language signals on the Jeremy Vine Show revealed three key emotional states: Contrition, suspicion and a subliminal desire for control and power.

The contrition was clearly the overriding theme and the one she was keen to promote consciously.

The dramatic, high-octane Roxanne we saw in the Celebrity Big Brother house had gone and in her place we saw an unsmiling woman sitting with slumped shoulders, tired, hooded eyes and a low vocal tone.

Her head shook from side to side as she offered a 'massive' apology and explained that she needed to become a 'better person'.

This new, contrite Roxanne clearly impressed fellow guest Alistair Campbell who, despite never having watched reality TV apart from his own short stint of Comic Relief's Apprentice, felt qualified enough to pass judgment on the genre and to reassure us Roxanne was a good egg because he had chatted to her backstage.

There was a hint of a tear glinting in the corner of Roxanne's eyes at this first flash of uninformed kindness.

The body language traits of suspicion came when she was called out about comments from ex-colleagues who had criticised her for similar behaviour in the past.

Roxanne's facial expression changed from humble to a much more knowing narrowing of the eyes as she seemed to put those comments down to "enemies from the past".

The hint of a subliminal desire for control and even power came from Roxanne's hand gestures, which were strangely incongruent with her mea culpa delivery.

For most of the interview the hands we'd seen either clutched to her chest or waving dramatically in the house remained placed in a forward steeple gesture with the fingertips and thumbs touching and pointing to the front.

This might have been a conscious attempt to control her emotions and suppress any gesticulation, but it is also a power gesture favourite of Angela Merkle and President Trump, who use it to imply dominance and emphatic detailed thinking.
