WrestleMania XXV

WrestleMania XXV (or The 25th Anniversary of WrestleMania or WrestleMania 25), was the twenty-fifth yearly WrestleMania professional wrestling Pay-per-view produced by World Wrestling Entertainment and took place on April 5, 2009 at Reliant Stadium in Houston, Texas. It was the second WrestleMania held in the state of Texas, with the first being WrestleMania X-Seven, at the Reliant Astrodome, also in Houston, which was held in 2001. The tagline for the event was ""Everything is bigger in Texas, especially WrestleMania"." "Cowboy" by Kid Rock was used in the first promotional advertisement for the event. While WWE calls it the 25th Anniversary, it is only the 24th anniversary as WrestleMania I cannot be an anniversary of itself.
