'Sledgehammer' superstars Fifth Harmony will kick off their headlining north American tour tonight with a show at the Regency Ballroom in San Francisco and they can't wait. 

Earlier this morning, Normani Kordei took to her official Twitter page and confirmed that rehearsals are now over so this really is the beginning of the jaunt: "Last day of rehearsal was today meaning our show is complete! WHO'S READY FOR THAT REFLECTION TOUR?"

Songstress Ally Brooke Hernandez explained to her 962,000 followers that she's on the tour bus heading to the venue and is "ready for adventures". The girls also shared a tweet from their collective account, writing: "Can y'all believe there's just 1 DAY until #TheReflectionTour starts?? We're beyond ready to see ur beautiful faces!!"

Back in January, the beauties revealed what they're most looking forward to about this tour and Kordei explained: "The fact that we have this new music is going to make this tour different. The fans are going to have a much better experience and it's going to be a lot cooler for them and for us, together."
