The 23-year-old will kick off her Revival tour on May 6 and said she can't wait to get started, reported Us magazine.
"I'm so excited - it's going to be big. I haven't toured in two years. It's going to be really emotional. I want it to be real, and I want it to feel like they're (fans) a part of the experience with me," she said.
Gomez's last series of shows were part of her Stars Dance Tour in 2013 and 2014, but a number of dates were cancelled for "personal issues".
She only revealed the real reason behind the voluntary rehab stay in October.
