American singer Lady Gaga sang in French during her performance at the Paris Olympics opening ceremony.

The 38-year-old hid behind a plume of pink feathers as she walked down a set of golden stairs next to the River Seine, close to Notre Dame cathedral.

The Paparazzi singer wore a black bodice with a detachable black and pink ruffled skirt as she sang alongside a group of dancers holding round pink, frilly props.

The singer is also reportedly set to perform a version of Edith Piaf’s La Vie en Rose alongside Celine Dion as part of a glittering conclusion to the first ever opening ceremony being staged outside a stadium.

So far the event has seen a total of 85 boats carry the team delegations on a six-kilometre journey through the centre of Paris, with more than 300,000 spectators lining the banks of the river.
