The global trek will be the 30-year-old star's first proper tour since co-headlining the Cheek to Cheek Tour with Tony Bennett between 2014 and 2015, reported Entertainment Weekly.
The tour supports Gaga's fifth studio album, 'Joanne' - her first solo effort since 2013's 'Artpop' - which spawned two singles.
In order to promote the album, the "Bad Romance" hitmaker has already released the two tracks from it- "Perfect Illusion" and "Million Reasons".
The songstress also teased the news on social media by posting a GIF of herself promoting the tour.
