On Oct. 29, Martina McBride hit the stage at the Grand Slam for Children Benefit Concert, which was set up by the Andre Agassi Foundation. At the show, McBride performed a few of her hits and also performed a duet with her good friend (and Train frontman) Pat Monahan. The 45-year-old looked beautiful, wearing a gray dress that flaunted her killer legs and a sparkly black leather jacket.

Along with other musicians like pop-rock outfit Train, soulful singer-songwriter Smokey Robinson, and swingin' crooner Michael Buble, McBride helped the Andre Agassi Foundation to raise a whopping $26.1 million, thanks to ticket sales, a silent auction and hefty donations from benefactors like businessman Kirk Kerkorian. According to The Sacramento Bee, all of the funds collected from the 16th annual Grand Slam for Children Benefit Concert will go to the "Andre Agassi College Preparatory Academy (Agassi Prep), a tuition free public K-12 charter school serving students in historical West Las Vegas."

Kudos to Martina McBride for once again doing her part to make the world a better place!
