Celebrity tattoo artist Kat Von D has accused her ex-fiance Jesse James of cheating on her with 19 other women during their relationship.

Von D began dating the TV mechanic just two months after he divorced actress Sandra Bullock last year amid rumors of infidelity.

Now the tattooist claims James was also unfaithful to her after opening up about their September split for the first time.

In a post on her Facebook.com page, she writes, "Today I encountered the 19th girl to add to the list of people Jesse cheated on me with during this last year. I know I deserve a big fat 'I told you so,' from everyone, and wish I didn't have to say, 'You all were more right than you'll ever know,' but you were."
 
Von D insists she's moving on from the "toxic relationship" and admits she pities James for "seeking validation" with a slew of alleged conquests.
 
She adds, "I think it just made me sad today to imagine him still in that dark place - where seeking validation through the attention of women takes precedence over being a good father, a sincere friend, a better coworker, and a happy individual."
