A good friend of mine met, through an online dating site, a woman who did this type of thing - claimed to be an insider in the "showbiz" scene, was a former Playboy Bunny, racecar driver, nurse, was the illegitimate daughter of Janis Joplin and John Lennon (!)... I thought she was nice and all until I actually met her, and I realized she was totally batpoop insane.
FWIW, whenever the "veto" threads pop up, this woman is the only type I would flat-out veto (or basically say that I will not -ever- have anything to do with). Ever. Delusional psycho? Yeah... no.
Anyhoo... apparently, some women end up making these "soap opera" lives up for themselves, too. Like real life isn't crazy enough!
