Kevin Federline's ex-girlfriend Shar Jackson has dubbed the star's recent weight gain "daddy weight," putting it down to him gaining full custody of his kids with ex-wife Britney Spears.
Federline was granted full physical custody of 2-year-old Sean Preston and 1-year-old Jayden James last year after Spears failed to adhere to court-ordered medical tests. The troubled singer was also stripped of her visitation rights to the boys in January but the former couple has since agreed a new deal to let Spears have limited access to her children.
Federline has embraced his role as a full-time father but has been spotted looking noticeably fuller-figured recently.
Jackson blames his weight gain on spending more time at home with his sons.
She tells Us magazine, "It's daddy weight! When you are a full-time parent, sometimes you can't focus on you. If gaining a few pounds is your only problem, life's not too bad!"
Federline's representative has also confirmed the 29-year-old is not bothered about piling on the pounds, saying, "He's a stay-at-home dad, and people tend to gain weight when they are home with the kids. He's very happy with the way he looks."
