Star Magazine reports that Shar Jackson, Kevin’s Federline’s on-and-off ex-wife is 6-week pregnant with his baby! This will be the third baby they have together, along with 2 with Britney Spears.

Shar got a positive result from a home pregnancy test, which was confirmed by a visit to her gynecologist a few days later; currently she’s about 6 weeks along. And the person who’s likely going to be shocked most by the news? Britney, who has long resented her ex’s closeness with Shar. A Spears’ insider shares her prediction with Star, “Britney’s going to freak – she’ll see this as a slap in the face.” A source reveals to Star, “Shar wants to tell Kevin, but she keeps getting cold feet! She’s really scared of what he’ll say – if he’ll be excited or furious. She said, ‘What if he doesn’t want another kid?’ After all with her two, and Brit’s two, he’s got his hands full already!” “It would be Shar’s dream for them to get married and have another baby. She’d love to be living the family life with Kevin.”

You would think after her first two that Shar Jackson would’ve gotten wiser and stopped. I think I’ll have better luck trying to figure out how to calculate the speed of light than how a douche like K-Fed gets around planting his loser seeds.

UPDATE: According to US Weekly, Shar Jackson is rejecting these reports, saying she is not pregnant with K-Fed’s baby, or pregnant at all for that matter. Uhhh… Well, think of it like those Pringles commercials. Once you pop, you can’t stop.
