Friday singer Rebecca Black steps out in Sydney with girlfriend Veronika

Her face was known around the world when she found fame at 13-years-old with her viral hit Friday.

But Rebecca Black, now 25, looked completely unrecognisable as she posed with fans on the streets of Sydney this week while out with her rumoured girlfriend Veronika.

The American singer showed off her tattoos and piercings as she walked through the city streets with Veronika. 

When Black first released Friday at age 13, she received widespread backlash online and was viciously trolled

Opting for a casual tracksuit, the songstress added fresh white trainers and an oversized hoody, which she wore up to stay dry in Sydney’s wet weather.

She tied her brunette tresses back and added golden hoop earrings while opting for a lowkey make-up look.

Meanwhile, her girlfriend Veronika wore a blue hoody and black trackies.

Rebecca is currently touring Australia with her new music, which is a far cry from the low-budget pop of Friday.

Earlier this week she appeared on Today, to promote the tour.

‘I’m so excited to be here in Australia now and to be almost 12 years after [Friday],’ she said.

Rebecca was stopped by countless fans on the street and seemed happy to pose for selfies with all of them 

The star has been in Australia to promote her new music and to perform a few concerts 

‘I just played a sold-out show in Melbourne, and to be able to build an audience that really resonates with what I’m doing now as opposed to this thing from back in the day, I feel really grateful.’

When Black first released Friday at age 13, she received widespread backlash online and was viciously trolled.  

It was also revealed at the time that her mother had paid $2,000 for the pre-written song, which was purchased from a musical composition and production company in Los Angeles.

The song went viral for being overwhelmingly ‘bad’ and was mocked by comedians and the public alike, though some called it ‘sickeningly catchy’ and it made her an overnight star.

Just three months after it was released, the video had amassed more than 166 million views on YouTube, but the majority of its engagement was negative and at one point it had received three million ‘dislikes’.

Black spoke to The Daily Beast after the song’s release, saying: ‘Those hurtful comments really shocked me. At times, it feels like I’m being cyber-bullied.’

In the years since, she has been able to continue her music career on her own terms and has also become a successful influencer, boasting almost one million followers on Instagram.
