Nicki and her wild 'n crazy hair are currently on tour with Lil Wayne until the end of the month, then she'll have just a little bit of downtime before heading on the road with Brit in June. The first scheduled appearance is June 17 in Sacramento, Calif.
Britney just started performing again, with short sets in Las Vegas and San Francisco at the end of March, and her full-length summer shows sound like they'll be pretty spectacular -- especially with Nicki as the opener. Bring on the glitter and bodysuits!
