Gaga’s performance – which also featured a troupe of dancers from the revered Moulin Rouge cabaret – was the first of many musical acts dotted along the banks of the River Seine in the first-of-its-kind outdoor opening ceremony.
It’s her biggest performance to date, topping her half-time show at the 2017 Super Bowl.
It was originally rumoured Gaga would sing La vie en rose by French songstress Édith Piaf, as she performed the hit in the Oscar-winning film A Star is Born, though she proved the punters wrong.
Death-defying stunt over Paris stuns opening ceremony
Mon Truc En Plumes quite literally translates to ‘My thing made of feathers’ in English, making Gaga’s set of pink feathers – and black feathered headpiece – extremely apt.
Olympic officials largely kept the details of the opening ceremony under wraps ahead of the actual show, with many acts and elements a complete surprise when they happened.
Joining the 7000 athletes on the River Seine was more than 3500 actors, dancers and musical performances, all working together to bring a vision from artistic director Thomas Jolly to life.
Viewers were taken through 12 tableaux encapsulating all-things Parisian excellence, with the scenes set all throughout Paris’ historical sites, bridges and rooftops.
