Sacha Baron Cohen makes a surprise appearance as his alter ego Borat at comedy club in Sydney

He’s been living a quiet and private life away from the Hollywood spotlight in Sydney with his family.

But Sacha Baron Cohen returned to the spotlight on Saturday, as he made a surprise appearance at a comedy club in Moore Park’s Entertainment Quarter. 

According to The Daily Telegraph, the British funnyman, 49, dressed as his alter ego Borat and surprised fans as he arrived on stage at the end of the showcase.

‘He was a surprise guest at the end of the showcase,’ one audience member said.

‘There were about 100 people in there. They’re trying something new,’ the onlooker explained.

It comes two weeks after Sacha left fans stunned when he stormed the stage as his original alter ego Ali G.

He reportedly performed two comedy showcases at the comedy club, with each set lasting for 20 minutes.

An audience member told The Daily Telegraph, everyone was required to put their phone in ‘locked pouches’ before Sacha came on stage – presumably to prevent the performance being leaked online.

‘[Sacha] had everyone in stitches,’ the onlooker said.

Ali G was the comedy persona that launched Sacha on the path to stardom.

The satirical character debuted on British TV program The 11 O’Clock Show in the late ’90s, before later appearing in the self-titled spin-off Da Ali G Show in 2000.

Sacha is currently living in Sydney with his wife, Australian actress Isla Fisher, and their three children.
