In response to a comment from kiki, I thought I would fill you in on four possibilities. The only four party happy starlets I know who are maybe pregnant are:
Christina Aguilera – BUT she was publicly drinking the other night, and so she is not pregnant.
Jessica Biel – Her publicist says she got sick recently due to jet lag. Uh huh. JB's most recent photo is below.
Lindsay Lohan – Check out the photo below for the baby bump.
Sarah Michelle Gellar – not really party happy, and she does not seem to be the motherly type.
