Tiger Wood's mistress Rachel Uchitel dances around 'Bachelor' Jake Pavelka

This is officially Elin Nordegren's nightmare. Imagine -- if you will -- how you would feel if your husband's (alleged) mistress got a TV gig as a result of their affair.

Rachel Uchitel did her first interview as an "Extra" 'secret weapon' correspondent last night. She got to dish with, of course, an eligible bachelor, none other than 'The Bachelor's Jake Pavelka.
