"Jesse and Kat don't see any reason why they should wait to trade vows," a source close to the couple said. "They are madly in love with each other and want to make everything official."
One person who's not so thrilled about the engagement? James' former mistress, Michelle "Bombshell" McGee, and she has a message for his new fiancee.
"Kat, what in the world are you thinking?" McGee told RadarOnline. "I was with Jesse during his marriage -- the guy's not faithful, he doesn't have a faithful bone in his body!"
McGee continued, "If he did it to me, if he did it to Sandra, he's gonna do it to you, too -- once a cheater always a cheater."
It seems like McGee might just be the voice of reason in this situation.
James and Von D made their first public appearance last September, just six months after James' marriage to Sandra Bullock fell apart due to his affair with McGee. They announced their surprise engagement on Jan. 20.
"I have never met anyone so kind and loving and committed to making the world a better place every day," James told PEOPLE about Von D. "My love for her is beyond description. So honored that she said 'yes.' Growing old with her is going to be a f***in' blast!"
Von D also gushed to Us Weekly about James.
"I feel really lucky," she said. "I think in the past I thought I knew what love was. I think I am growing up a lot too and realizing the truth in a lot of things and feel really blessed now," she said.
This will be the fourth marriage for James, and the second for Von D, who divorced tattoo artist Oliver Peck in 2007.
