The Clinton-Bush post-presidency lovefest took on a new dimension tonight as another former president - George W. Bush - joined Bill Clinton for the NCAA men's basketball final in Arlington, Texas.

Clinton and George H.W. Bush, whom he defeated to become president in 1992, have been pals for years, appearing at various functions, including in 2005 when they teamed to lead relief efforts after the 2005 Asian tsunami.

"My husband, Bill Clinton and I have become friends. And Bill visits us every summer. We don't agree politically, but we don't talk politics," Barbara Bush told C-SPAN last year.

But until the game today, George W. and Clinton had not been seen much together outside of all-presidents-on-deck functions.
