"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 tells PEOPLE exclusively. "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 pair have been dating since last summer, following the collapse of James's marriage to Oscar winner Sandra Bullock. Their divorce was finalized last June.
"There is no one else for me. He's the one," The LA Ink star tells PEOPLE.
Asked if she will move from Los Angeles to Austin, Texas, to be with her fiancé, Von D replied, "If only it were that easy. Having two places we call home will be good for now. In the end, home is where the heart is, and my heart's with him."
James, 41, and Von D, 28, have been engaged in Twitter PDA in recent weeks. On Jan. 13, James Tweeted: "They say True love will always shine through. The only reason I started Twitter again? so I could publicly profess my love for @thekatvond."
She responded: "Thank you always supporting me and believing in everything I do. But most of all, thanks for being my best friend."
