Charlene and Albert's happy dance

Eyes for each other - Charlene and Albert dance the night away at the annual Red Cross Gala Ball in Monaco on Friday night.

Princess Charlene of Monaco last week looked as at home as ever on the sidelines of the pool as she cheered on South Africa at London's Aquatic Centre.

Come Friday night, the Olympian swimmer looked equally at ease in black tie glamour back on her adopted home turf in Monaco as she danced, taking a lead from Prince Albert - also an Olympian, though rather more familiar with the ice of the bobsleigh track than laps of a pool - at the principality's annual Red Cross Ball Gala. 

Dispelling rumours of depression and marriage problems, the South African native and her husband, who this July celebrated their one year anniversary, looked relaxed and happy together, Charlene sporting a gold sequinned dress with a flowing white skirt.

It was a fitting outfit to end the week - Charlene had watched her close friend, South African swimmer Chad de Clos clinch a gold medal, beating megawatt US swimmer Michael Phelps by 0.2 seconds in the 200m men's butterfly.

The couple watched the final and other races tensely - and were on their feet to applaud the swimmers' best efforts.
