    Andy Roddick

    Who is the bigger cheerleader, Andy Roddick’s model wife, Brooklyn Decker, or his English Bulldog, Billie Jean (appropriately named after the former tennis great, Billie Jean King)? Although a bit too large to fit under the seat of an airplane, the pooch still travels to most of Roddick’s games. In a 2010 ESPN article, Roddick quipped, "We’ve had to keep up her self-esteem, because the airlines have deemed her too fat to fit on a plane. So we have to constantly shower her with love and build up that self-esteem and tell her she's beautiful."

    Decker tweets, "I mean..."

    We are similarly speechless about Billie Jean's cuteness.
