The British rock star also teased some possible collaborations that could feature on his third album.
The track features a backing band made up of Ed Sheeran, Griff, Lewis Capaldi, Sam Smith and Yungblud.
This year's event was held in Hungarian capital, Budapest, with the ceremony hosted by Saweetie.
The rising star's tour was originally planned September this year, but was unable to go ahead due to the coronavirus pandemic.
Yungblud has announced a new short film based on his 2020 song ‘Mars’ is in the works, in conjunction with Mercury Studios and Interscope Films.
‘When you find an artist who is so undeniable themselves … they literally are part of building the foundations about what you base your life upon.’
The run kicks off January 26 in Athens, Georgia.
The song premiered last month on BBC Radio 1.
The fast-rising star's headline shows begin on September 27 at the Brighton Dome. A London date comes at Alexandra Palace on October 1.
‘I wrote ‘fleabag’ in a really dark time of my life, when a lot of people around me had an expectation about what I should be.’
Streaming from London's Wembley Arena on August 15, the 90-minute special will be hosted by BBC Radio 1's Greg James and Clara Amfo.
"I feel like I’ve been waiting for the call (for this) my whole life!" Yungblud said.
Scotland will still have restrictions in place in August, meaning Dominic Harrison’s two Glasgow dates will now take place in December.
‘Madonna is a massive idol of mine, I admire every move she artistically made. I wanted to take the classic, add some YUNGBLUD energy and shake it the f**k up!’
The star's appearance at West Hollywood club marks his first performance to a live audience since his album 'Weird!' arrived last December.
