Washington, Nov 21 : Britney Spears blames ex-hubby Kevin Federline’s failed musical career for their marriage break-up.

The stunner said that her romance with the rapper was over long before she filed for divorce, as he was too busy building his own career to spend time with her, reports Contactmusic.

She said: "He started to do an album for himself and he started to do things for himself, and I just never saw him anymore."

However, she was still devastated when she realised the marriage was over, she says: "When it ended I felt so alone. I didn''t really wanna think about the reality of it. I never faced it…I just ran."

The singer said that the split brought back painful memories of her split from Justin Timberlake.

Spears said: "He was a part of the magnitude of what I had become. So when he was gone I was like, ''What am I supposed to do with myself?'' I was devastated." (ANI)
