If there is ever the right time and the right place to break into a spontaneous cover of Bon Jovi's definitive anthem 'Livin' on a Prayer,' it's in the band's home state of New Jersey. And that's just what country cutie Taylor Swift did last night while performing at the Prudential Center in Newark, N.J., which is Jovi's backyard and stomping grounds.

Wearing her pretty purple stage dress and seated on a stool while cradling her acoustic guitar, Swift broke into the song's famous chorus, "It doesn't make a difference if we make it or not / We got each other / And that's a lot for love / We'll give it a shot / Whoa, we're halfway there / Whoa, livin' on a prayer / Take my hand / We'll make it I swear / Whoa / Livin' on a prayer."

The crowd sang along with her, nearly drowning out her voice and belting out those lyrics with a passion that could not be contained. That's what happens when you sing Jovi in Jersey, Taylor. It was a good move for Swift, who is known for covering locals during her sets, like she did in Canada the other night. She shows her appreciation for local culture and legends by offering her takes on their songs. It's like a brilliant public relations tactic that benefits the fans, as they get to listen to their heroine offer her versions of classic songs that she didn't write.

After the chorus of 'Livin' on a Prayer,' Swift sailed right into her own hit 'You Belong With Me.' Jon Bon Jovi and Richie Sambora should be proud of how Swift handled their classic rock juggernaut.
