Though Britney Spears is itching to have a baby, her hubby Kevin Federline, who’s son through his previous romance with Shar Jackson was born back in July, isn’t in a hurry. “Kevin thinks it’s way too soon for them to have a child together,” a friend of Federline told Star magazine. “Britney’s desperate to have a baby and she’s been literally begging Kevin to make her pregnant. But he keeps telling her, ‘No, Britney. I don’t want another kid yet. My son isn’t even a year old’.” So in the meantime, the pop princess is “just trying to concentrate on her career,” according to a friend.
