Britney Spears has done it again. After already making two very big tattoo boo-boos, the only difference this time is it may take her a little longer to realize she's going to regret it. Spears and her new beau, Kevin Federline, recently got matching tattoos to declare their love for each other. I wonder if they'll also get mutual removals like Angelina and Billy Bob when they split up - how romantic!
