Sydney Sweeney‘s floating on cloud nine … not only did she got Instagram official with Scooter Braun — but she took a high-flying tour of a famous bridge Down Under.

The actress was spotted in Sydney, Australia, Sunday taking The Harbour Bridge climb … a tour where patrons can walk along the underbelly and enjoy breataking views of the city’s famous harbor.

Sweeney — who was joined by her father Steven Sweeney and her pal Kelley McCartney — had to strap into a harness to safely walk across the bridge … and she and Kelley stopped to pose for a few pics on the way.

It seems Sweeney’s feet are barely touching the ground these days — not only is she touring tall landmarks, but she also sat on Scooter’s shoulders at Stagecoach in one of the photos she posted to hard-launch their relationship on IG.

Obviously, we know they’ve been dating for months … but, she only just went official on social media — an important step in modern courting — with Scooter.
