Pop star Katy Perry has left a permanent mark on Hollywood after taking part in a handprint ceremony outside the famous TCL Chinese Theatre in Los Angeles on Tuesday (08Sep15).

The Firework hitmaker imprinted her palms in cement close to the Hollywood landmark in a joint ceremony with her fashion designer friend Jeremy Scott.

The big moment came ahead of the premiere of Scott's new documentary, Jeremy Scott: The People's Designer, which features a cameo appearance by Perry, as well as Miley Cyrus, Rihanna and Paris Hilton.

Scott became the first fashion designer to be immortalised on the pavement outside the Chinese Theatre, and he tweeted, "Still can't believe this happened tonight!!! To be the only designer in history to leave their hand prints in the iconic collection of stars (sic)."
