Rejoice, Lady Gaga fans. The Mother Monster is making her first concert appearance in the Hammer.

HECFI announced on Friday the New York freak-pop phenom is bringing her Born This Way Ball Tour to Copps Coliseum on Feb. 17, just in time to help in getting that wince-inducing taste of Valentine's Day out of your mouth.

Tickets go on sale on Dec. 7 at 10 a.m. through Ticketmaster.ca — and will undoubtedly sell out as fast as Gaga changes her hairstyle.
