She’s known for her fierce and Sєxy performances on stage.

And while Katy Perry was just an audience member on Wednesday at Broadway’s Finding Neverland, she stole the limelight once she was backstage congratulating the actors.

The 30-year-old displayed her cleavage in a plunging cut-away top as she posed with Glee alum Matthew Morrison, who plays JM Barrie.

The pop star had a bohemian flair to her outfit, which featured multi-coloured tᴀssels and a long maxi skirt.

Wearing her hair over her shoulders, the Roar hitmaker posed with the castmembers of the show, including two of its canine actors.

Morrison, 36, was still in costume as the celebrated playwright in a tuxedo and white bow tie.

While co-star Laura Michelle Kelly wore gorgeous turn of the century night gown while cuddling up to Katy.

Speaking of the challenges of performing onstage night after night, Morrison told CBS in July: ‘I went into this really wanting to do everything I could.

‘I started my career as a dancer and stuff and I told Mia Michaels the choreographer, “Let me do everything,” But that was my 26-year-old self talking and I’m 36 now so it’s a little harder.’

Finding Neverland centres on how JM Barrie came to write his most famous work Peter Pan.

‘I’ve done a lot of great roles on Broadway, but being the outright leader of a show is so different and I often call my friend Marissa Jaret Winokur, who was the lead of Hairspray, the actor admitted.

‘You carry this $15 million show on your shoulders and there’s a lot that comes with it.’

The film version of Finding Neverland (2004) starred Johnny Depp, Kate Winslet, and Freddie Highmore.
