Kevin Federline bombarded with boos

Pop Babe Britney Spears made sure not to steal the spotlight from husband Kevin Federline as he celebrated the release of his debut album, Playing With Fire, on Tuesday reports People Magazine.

Spears donned a pink wig and oversized white sunglasses at the after-party in Hollywood, where she blended in perfectly with the Halloween night revelers, the rapper's rep confirms to PEOPLE.

Earlier in the evening, Federline performed his song "Privilege" on L.A.'s KIIS 102.7 FM stage at the West Hollywood Halloween Carnaval to kick off his promotional tour. But before going onstage, he admitted that the demands of his fledging career mean he's spending less time with his family.
