Watch Katy Perry absolutely nail epic inauguration finale with hit track 'Firework'

Joe Biden's evening inauguration special has come to a close with a spectacular performance by Katy Perry, complete with an impressive fireworks display from the US Capitol.

Foo Fighters, Justin Timberlake, Demi Lovato, and Bruce Springsteen all performed in the celebratory television special hosted by Tom Hanks, but Perry's powerful performance was just the right note to end on.

Orlando Bloom gushed that he's "one proud partner" after Katy Perry's 'Celebrating America' performance.

The 44-year-old actor cried "a tear of joy" when the 36-year-old pop star belted out her mega-hit Firework during the TV special in honour of President Joe Biden's inauguration.

And Orlando can't wait for the couple's four-month-old daughter, Daisy, to be old enough to see her mother “play [her] part in a moment in history".

Alongside a clip of his fiancee's powerful performance of her 2010 hit, Orlando wrote: “One day our little girl will grow up and see her mother play her part in a moment in history that we hope will heal, we hope will unite, we hope, we love.

“One proud partner here with a tear of joy."

Meanwhile, a source previously said that Katy is "obsessed" with her little girl, and being a mom has taken her relationship with the ‘Carnival Row’ star - who she got engaged to in 2019 - to a whole other level.

A source said: "[Katy] has been incredible with her daughter and is obsessed with her. The couple and their love for one another had grown to a level they didn't even expect since the arrival of their daughter."

Although the Never Really Over singer went back to work just six weeks after giving birth in order to shoot a music video, Katy recently insisted her little girl will always be her main priority.

She said: "She'll always be the number one most important thing ever, naturally. But I love being a working mom. I don't think there's anything negative about it. It's like, 'Wow, you can do that and that?' All right! That's a woman, you know?"

And the 'Smile' star has a newfound appreciation for the hard work mothers do since becoming one herself.

She tweeted: "Popular misconception: being a mom isn't a full-time job ...part 2: when a mom finally goes back to work (whatever profession they do) it's not like they been coming from months of "time off..." she's coming from a full-time job... of being a mom, lol ... Part 3: call your mom and tell her you love and appreciate her and advocate for paid family leave! Part 4. I love my job. (sic)"
