Just what on earth is going on with Zac Efron?

Zac Efron has insisted he is ‘happy and healthy’ after being hospitalised over the weekend, but it’s been a challenging time for the movie pin up.

Just what on earth is going on with Zac Efron?

It’s not the first time Zac has hit the headlines with his physical health, with drama surrounding the star since he shot to fame as heartthrob Troy Bolton in High School Musical in 2006.

This latest incident saw the actor in hospital on the party island of Ibiza when he dived deep into a pool at a villa early Saturday.

Zac had taken in ‘a large amount of water into his lungs’ after he made contact with the bottom of the pool.

The leading man had ‘showed signs of distress’ and was ‘momentarily dazed’ in the wake of the incident, sources told the outlet, at which point security officials rushed in to assist him.

The Ibiza accident comes 11 years after a near-death experience which saw the star slipping in a puddle of water while running in socks in his home and smashing his chin into a granite fountain, leaving his chin bone ‘hanging off his face’.

Zac later told Entertainment Tonight that he nearly died after the freak injury, explaining: ‘It was funny. It sucks. I almost died, but we’re good.’

The movie star famously claimed the accident caused his changing appearance, which in recent years has caused a flurry of speculation that he has undergone cosmetic surgery.

Zac has always denied he has had any plastic surgery, instead insisting the masseter muscles on the inside of his face and jaw ‘compensated’ for his 2013 injury, leading to his changed shape.

The High School Musical star even claimed he didn’t know his transformation had gone viral on social media until his mother told him about the plastic surgery rumours.

Despite all his efforts to bring truth to the rumours, Zac has been hit with a fresh batch recently after fans watched his most recent hit, A Family Affair.
