BRITNEY SPEARS - FEDERLINE KEEN TO LOSE `DADDY FAT'

FEDERLINE KEEN TO LOSE `DADDY FAT'

BRITNEY SPEARS has mixed feelings about her husband KEVIN FEDERLINE's "daddy fat" and occasionally insists he hits the gym. Dancer-turned-rapper Federline admits he has gained "sympathy" weight both times the pop superstar has fallen pregnant - and he struggles to lose it. He says, "I gain the sympathy weight and she loses it (weight)in two weeks after she has the baby... It's daddy fat. It comes and goes. "She (Spears) goes through different feelings about it. Sometimes she'll tell me to get my butt in the gym and sometimes it doesn't bother her."
