CHRISTINA'S CHRISTMAS

CHRISTINA AGUILERA’s kickboxing instructor got a great Christmas gift! The cleaned-up Dirrty Girl overheard him telling a pal on the phone that he wouldn’t be attending a kickboxing tournament in Hawaii this year because he just couldn’t afford it. Christina, who’s loving the kick-ass shape he got her in for her tour (we second that emotion, babe!), ponied up all expenses for him to go and kick butt in Hula-Land – and even bring his wife along to watch.
