"You know sometimes the public and press gets it wrong. This is one of those times. 2010 was actually the best year of my life because I fell in love with my best friend. An amazing woman who stood behind me when the world turned their backs," James told the magazine. "I have never met anyone so kind and loving and committed to making the world a better place every day. My love for her is beyond description. So honored that she said 'yes.' Growing old with her is going to be a f----n' blast!"
The 28-year-old Von D feels the same about the former Monster Garage star. "There is no one else for me. He's the one," she said.
James recently took to Twitter to profess his love for his fiancé. "They say True love will always shine through," he wrote. "The only reason I started Twitter again? so I could publicly profess my love for @thekatvond."
