Britney Spears' ex-husband Kevin Federline and her father are reportedly going into business together - as restaurateurs. Professional caterer Jamie Spears and the dancer/rapper have taken over a Mexican restaurant in Los Angeles. The restaurant, Casa Cordobes, has been a favourite of Federline's for years and he once ate there with Britney. Despite his ongoing custody war with Britney, Federline has maintained a friendship with his former father-in-law - the pair was spotted playing golf together earlier this month (Mar08).
