Tammy Hembrow and her new toyboy lover Grayson Te Moana are fast establishing themselves as red carpet regulars. 

The new It-couple ensured all eyes were on them as they attended the opening night of Disney's The Lion King at the Capitol Theatre in Sydney on Thursday. 

The influencer, 31, and her 22-year-old boyfriend matched in all-black ensembles as they posed up a storm on the media wall. 

Tammy chose a fitted black dress that showed off lots of skin thanks to cut-outs at the side and a daring thigh-high split. 

She also had her ample, surgically-enhanced assets on show in the low-cut number, which was cut to a floor length. 

Tammy channelled Pamela Anderson by wearing her blonde locks in a messy, loose bun. 

For makeup, she opted for a rosy makeup look with lots of highlighter and a matte pink lip. 

She finished the ensemble with a black envelope clutch purse and matching high heels. 

Grayson also chose a monochrome look, including a black blazer with no shirt underneath that flashed his chest. 

He added a pair of wide-cut trousers, also in a dark tone, as well as patent leather loafers. 

The loved-up pair could not keep their hands off each other, kissing and cuddling on the red carpet. 

The couple 'hard-launched' their romance in February at the Australian premiere of Wuthering Heights in Sydney. 

Tammy revealed that same month that she had struck up a relationship with Sydney model Grayson.

She appeared on the Hit Network Drive with Lucy Jackson and Nikki Westcott, where she was promptly asked for details about her new relationship.

The radio duo were probing Tammy for more information about her new man, and she seemed sheepish about spilling the beans.     

'You are a hot, into each other couple right now, and I'm loving that for you, babe,' Lucy said. 

Still reluctant to divulge details about her romance, Tammy replied, 'Look, I'm having a great time.'

This did little to placate the hosts, who continued to probe Tammy for information.

'You guys can do your own investigations,' she said. 'I'm not ready.'

Tammy admitted that the reason she wasn't keen to give up too many details was that she wanted to 'protect' Grayson and their relationship.    

'The thing is, I like being an open book, I want to be an open book, but this is something I just want to protect a little bit,' she said.
