The ex-lover of convicted wife killer Gerard Baden-Clay has fled to the United Arab Emirates and started a new life as a teacher using the alias 'Bridget Jones'.

Toni McHugh, 48, started an affair with real estate agent Baden-Clay while working for him at his Brisbane agency in 2008.

The pair - who were both married - would meet up to four times a week during a lengthy affair, but cut ties a year before Baden-Clay murdered wife Allison in 2012.

Tracked down by The Sunday Mail, Ms McHugh refused to comment on her fresh start and demanded her new workplace be kept a secret to protect her identity.

'This (name change) has been done for my safety and to allow some level of anonymity on a daily basis,' she told the publication.

Toni McHugh now teaches at an international school in the United Arab Emirates, and has been described as seeming 'like any other normal person'

Ms McHugh, who left her husband of 17 years to pursue a relationship with Baden-Clay, was forced to leave the Brisbane agency after his wife Allison found out.

Baden-Clay and McHugh called time on their relationship, but started things up again when Allison went missing in April 2012.

She was even forced to describe their affair at Baden-Clay's murder trial, which saw him sentenced to a minimum 15 years' jail in 2014.

In the aftermath of the trial, Ms McHugh was relentlessly pursued by the media for her on-again, off-again romance with Baden-Clay.

Shortly after doing rounds of media interviews, McHugh moved to Bali to volunteer as a teacher in 2015.

The following year, she lived in a villa in Bali's serene and tranquil town of Ubud.

But now, four years on from her Indonesian stint, McHugh has started afresh in the Middle Eastern country home to billionaires and royalty.

She teaches art classes at an international school, which has more than 1000 kids and 100 teachers.

The school is a large walled complex, with the high level of security suited for anyone wanting to go unnoticed.

Sources from the school have described her as seeming like 'any other normal person'.

'I wouldn't look twice at her if I didn't know anything about her, she just looks like an ordinary expat teacher,' a source told The Sunday Mail.

'A little reason of why she ended up here is probably because she faded into the general background of expat teachers.'

McHugh lives a low profile life, and uses the name 'Bridget Jones' on social media to keep in touch with friends.
