Christina performed at NMPA Awards 2014 and she sang Liar Liar from her first album Find Me, With Love from her last album and one of Bon Jovi’s songs Livin’ On A Prayer.
I guess that Christina got so amazing experience singing for Bon Jovi.
If you want to see Christina singing Liar Liar and With Love, watch it from 3:04 but i strongly recommend you to watch the whole video.
And again, if you want to see Christina singing Livin’ On A Prayer, watch it from 8:34.
