The pregnant ex-girlfriend of Britney Spears’ boyfriend Kevin Ferdeline plans to retaliate by releasing a single about being dumped. Actress Shar Jackson - who is the mother of Federline’s four-year-old daughter and is currently pregnant with his second child - is set to release a song about her experiences of being cheated on.

Jackson says, “I’ve written three songs about this whole thing for my band Mpulz.”
Spears reportedly stole dancer Federline away from Jackson last month.
