 Perry made sure to flaunt the daisy-shaped, $5M Neil Lane engagement ring her fiancé - Carnival Row star Orlando Bloom - popped the question with on Valentine's Day. 

 The beaming bride-to-be and the British 42-year-old are planning to marry in December, according to Us Weekly, sometime after her concerts in LA and Chicago on December 6-7.

'He's the kindest soul. He is the kindest man I've ever met and he shows up and he is such an encouragement spiritually, emotionally, and physically. I do not care to work out and he's like, "Let's go work out! Let's go and do hot yoga!"' Katy said on The Ellen DeGeneres Show last month.

'So that's kind of our love language - all things spiritual and working out and his son, who's eight years old...I guess this has definitely matured me.'

The on/off couple - who were first linked in January 2016 - rekindled their romance last year after 'taking a respectful, loving space' apart from each other in February 2017.   

It will also be the second time down the aisle for both as Orlando divorced Australian model Miranda Kerr in 2013 and Katy divorced English comedian Russell Brand in 2012.

After performing with a string orchestra wearing a voluminous b&w-dotted gown, Perry spoke about when she learned how to mediate in India a decade ago.

'Then all of a sudden I started doing it, and I found that I had more time and more energy - like an endless amount of energy - just investing in that 20-minute interval.  

'I'm really here because Transcendental Meditation is I would say, the number one tool that has changed my life. It's brought me so much balance and so much peace and stillness.'

Other performers at the Silence the Violence benefit included Australian rocker Jeremy Elliot, nine-time Grammy winner Norah Jones, two-time Grammy winner Mavis Staples, and the Celebration Gospel Choir. 

Katy was also in the Nation's Capital to judge the regional American Idol auditions being held Sunday-Monday for the 18th season, which premieres mid-late February on ABC.

Perry earns an eye-popping $25M per season of the formerly Fox singing competition, according to TMZ.
