Start your engines Sydney!

Zac Efron has touched down in the Harbour City for the red-carpet premier of his new movie ‘Mike and Dave Need Wedding Dates’.

He’s here with the hilarious Adam Devine (who you probably know from Modern Family), and they’ll appear at Event Cinemas in Parramatta tonight.

There is a bit of free time between now and then, and we do know Zac has already squeezed in a gym session.

Adam Devine did some sight seeing around Taronga Zoo yesterday.

So keep an eye out for Zac around the CBD today! If you spot him, tell us on Facebook!
