Having the same name as a celebrity can result in some fun identity-confusion -- unless you happen to share a name with internet punchline Rebecca Black.

So learned a model and self-described "fitness bikini competitor" named, yes, Rebecca Black, who recently watched in confusion as her Facebook friend list blew up from 800 to 73,000. Not long afterwards, she began getting nasty notes accusing her of hijacking the young viral sensation's page.

The elder Black blames the snafu on Facebook, which she says merged the women's pages together without her knowledge or consent.

It all seems to have been sorted out now -- she's back to a comparatively paltry 723 page fans -- but the resulting media flap got the 29-year-old model and personal trainer a whole lot of free publicity.
