Princess Charlene and Prince Albert cheer for their Olympic favorites

(CBS News) Monaco's Princess Charlene and Prince Albert II haven't been shy about showing their Olympic spirit at the London Summer Games.

They've been photographed in the stands, sitting side-by-side and even getting emotional at points during the competitions.

Princess Charlene was photographed cheering on South African swimmer and friend Chad le Clos in the men's 200-meter Butterfly race last week.

When he edged out Michael Phelps for the gold, Princess Charlene could be seen getting teary-eyed, as seen in pictures posted the U.K.'s Daily Mail.

Princess Charlene is an ex-Olympic swimmer, so she knows what it's like to be inside the Olympic pool. She competed with the South African female team in the Sydney Games in 2000.
