Zac Efron and Vanessa Valladares spark reunion rumours

Zac Efron made giddy fans’ dreams come true when he posed for pictures outside the Australian gym where he’s been buffing up considerably.

The High School Musical star is Down Under filming indie survival thriller Gold, co-starring alongside Aussie Anthony Hayes, who is also directing.

He showed off his supremely toned biceps in a black tank top and shorts, while he posed for selfies with bystanders on his way back to his hotel.

The 33-year-old carried a boom box, accessorised with a black beanie, sunglasses and New Balance trainers.

Zac was subjected to mockery over the summer for what some called his ‘dad bod’.

The Baywatch star made headlines when he supposedly split from 25-year-old waitress Vanessa Valladares last month, after a whirlwind summer romance.

But she was spotted sneaking out a different door of the same gym where Zac had been sweating it out with his personal trainer.

She was pictured sported a pair of black leggings, which she paired with a cheery orange and yellow sports bra and pink trainers.

An insider revealed last month that the pair had been looking at places to live together before the rumoured split.

They explained to the Sun: ‘Zac and Vanessa looked like the real deal. They were besotted with each other.

‘Zac has been renting a place by the beach in Byron Bay and by September Vanessa was living with him there.

‘They’d started to look at a few places but, sadly, fate wasn’t on their side.’

‘Zac’s work and the enforced distance has really taken its toll.

‘Friends hope they can reunite, but it seems their relationship was more like a holiday romance than they cared to admit.’

Zac, who has been living in Australia since March, met Vanessa while she was working at the Byron Bay General Store & Café earlier this year.
