The drama between Britney and ex-hubby Kevin Federline doesn't look like it's going away any time soon. In fact, they are dragging their friends and family members in the middle of their custody battle.

Too bad Alli doesn't want to have anything to do with the subpoena papers. (Photo courtesy of Gawker)Click the link to see X17.com's exclusive video of Miss Alli's tantrum.
