Monday’sAmerican Idol brought lots of surprises — both in terms of who made the Top 16, and Katy Perry’s new look.

The “Roar” singer and Idol judge stunned with a striking black ‘do — in stark contrast to the bright blonde looks she’s been serving up all season.

Perry’s long black locks stole the spotlight, and the songstress paired the new style with a big, bold golden cross necklace and an animal print top that truly came together to wow fans.

While many tuned in to see which of the Top 24 would be making it to the Top 16 — and which eight hopefuls would be getting the axe — fans couldn’t help but marvel about Perry’s look on Twitter.

Perry teased her bold look ahead of the show, sharing some snapshots to her social media, revealing both her hair and her ensemble.

“Roaring into the top 16 with ? vibes tonight, don’t forget to watch then vote!” Perry wrote.

Perry didn’t oversell it either — the show really did claw the competition down to size as the Top 16 were revealed, leaving more than a few contestants — including the pop star’s lookalike Hannah Everhart — high and dry.

Here’s who made it into the Top 16 on Monday’s episode, and the song they sang for America’s next big vote:
