Ulterior motive? Britney Spears ex-husband plans to move kids to Hawaii...

Leechy Kevin Federline is legally trying to relocate Britney's sons to Hawaii full-time with him and his wife.  

And check this... he expects to fund their lifestyle with DJ gigs. Haha, yeah riiiight. Fans have clocked that he only wants to move there because the child support cut off age is 19, and 23 if the child is in university or college full time. 

Britney's lustrous child support cheques are simply too good to lose so soon.
