THIS is the moment Shamima Begum exposes her deception over returning to the UK with a "cluster" of tell-tale signs, body language experts say.
Shamima Begum was 15 when she left her home in East London with two pals to join ISIS in Syria.
She was stripped of her British citizenship while she languishes in a camp in Syria.
Begum, now 21, recently claimed she was just a "dumb kid" when she joined ISIS and "didn't want to be the friend that was left behind".
In a string of TV interviews, she also insists she won't cause any harm if she returns to Britain.
But documentary Shamima Begum: A Faking It Special has exposed the signs that reportedly give her away.
Body language expert Dr Cliff Lansley highlights a cluster of three gestures in just seven seconds that he says show her deception.
He says: "What we have here are the eyes closed for about 15 frames, which is just about half a second.

“If I make a claim that I don’t want to hurt anyone, I’ll connect myself with that statement; I’ll say I don’t want to hurt anyone. But if I say I don’t want to hurt anyone and close my eyes while I’m using those words, we see that as a contradiction.
"It’s a deception indicator.”
The expert also points out how Begum exhibits an eye closure and a "hand roll" that could suggest she is faking it.
He added: “We get a half second eye closure, which is blocking herself off from that statement.
"The third thing is we get the hand roll, so you’ll see right at the bottom of the screen here the hand rotating.
“When we get three indicators across the communication channels inside seven seconds, we have a high degree of confidence that this is lacking credibility and she’s probably lying.”
In a recent interview, Begum moaned about not being able to watch the Friends reunion in the Al-Roj prison camp.
She also previously told how she spends her time watching ITV's Good Morning Britain in her tent and binging blockbusters such as Men in Black.
Begum, who now wears Western-style clothing - including Nike baseball caps and tight jeans - reveals she enjoys playing charades and dancing to Shakira in Zumba classes.

The documentary examines another interview from three years ago where she claimed she was "just a 19-year-old" with no weapons who "doesn't want to hurt anyone".
But Dr Lansley says she presents "two contradictory body language signals" that suggest otherwise.
He explains how Begum gives a "mouth shrug" that people usually display with they have "no confidence" in what they are saying.
The expert also points out how she gives another hand shrug, adding: "We’ve got a combination, which is corroboration, of ‘no confidence in what I am about to tell you.’”
Begum was just 15 when she fled school in 2015 with two pals to join the death cult.
She later wed an ISIS fighter and had three children, who have all since died.
But after the evil regime collapsed, Begum ended up in a refugee camp.
And soon after, then Home Secretary Sajid Javid stripped her of her UK citizenship to stop her from ever coming back.
Begum has previously told how she had no regrets about joining the death cult and was not fazed by seeing discarded heads in bins.
She also told how she had sewn ISIS bombers into their suicide vests.
But she insisted last week she had changed - claiming she was "young and naive" when she decided to leave the UK and join ISIS.
Footage from when her citizenship was removed has also been examined by the experts.
What did Shamima Begum do?
Begum and two pals – Kadiza Sultana and Amira Abase – ran away to Syria in February 2015.
Begum used her elder sister’s passport to flee with her Bethnal Green Academy friends.
The trio flew to Turkey and then crossed the border into Syria with the aid of smugglers.
Within weeks of arriving, Shamima was married to Isis jihadi Yago Riedijk, 27, from Holland.
They had two children who died from malnutrition and disease.
The couple were separated as they fled Baghouz, the village where a few hundred Isis fighters were holed up in a desperate last stand.
Shamima ended up in a Kurdish refugee camp where she gave birth to her third child.
Eldest sister Renu revealed that her family had lost contact with her for the “longest time” until .
She can be seen looking visibly upset as she brands the decision "heartbreaking".
But Dr Lansley believes she is faking sadness with a "pitiful face" that resembles a child pouting or sulking.
He added: "This was a very poor attempt from Begum to try and display sadness to attract sympathy to have her case reheard, appealed, to allow her to move into the UK.”
Begum lost a legal battle to return to the UK for a court appeal over the removal of her British citizenship in February.
The Supreme Court unanimously ruled in favour of the Government and said she cannot come back to the UK for a court case to reclaim her British passport for the safety of the public.
Lord Reed said her legal bid to reclaim her British citizenship should be postponed until she is no longer considered a threat to national security.
