PerezHilton.com is reporting that Britney Spears MAY be pregnant again. He has multiple sources confirming this (which of course he refused to reveal to me) as well as other sources saying that Britney has dumped her n'er-do-well husband Kevin Federline.
the items of evidence that Perez is offering up for proof of a pregnancy are as follows:

1. that Britney was rushed to the hospital last week with stomach cramps, which Perez says is not uncommon for pregnant women, I never experienced this but every pregnancy is different

2. that at the Kanye West/Verizon Wireless Grammy party that Britney and Kevin attended, she was not observed consuming alcohol- again, not proof but could be indicative of a pregnancy
3. according to a celeb tabloid, that Britney herself rubbed her belly in a Malibu store and told people, "That's right, number two!" Additionally, a friend of hers apparently told In Touch that "Britney is definitely pregnant again." Again- do we necessarily trust In Touch for their accuracy?
and
4. that it is apparent to those on the set of Will & Grace where Britney was shooting a guest spot, especially in the costume department.

Just waiting until this rumour is true
