Kevin Federline is gearing up for baby #5 -- and unlike the two kids he had with Britney Spears ... this one's a girl.
According to Kevin's now pregnant girlfriend -- ex-pro volleyballer Victoria Prince -- they're naming her Jordan ... because when the couple was deciding on names, they weren't sure of the sex and wanted something that could go either way.
Victoria's due in a couple months.
