Dozens of boats rolled down the Seine river with 205 delegations cheered on by over 300,000 people. The ceremony featured Lady Gaga as well as an emotional comeback by Celine Dion.

The opening ceremony of the Paris Olympics lived up to its expectations with a massive event showcasing French extravaganza, culture and diversity at its best.

Over 300,000 people flocked to the banks of the Seine River, watching and cheering on dozens of boats carrying the 205 national delegations, starting with Grece and closing with hosts France.

The event went off with only minor hitches after a rough start to the Summer Games. Following suspected acts of sabotage targeting France’s flagship high-speed rail network, a soggy but celebratory parade down the Seine River brought an official start to the Olympics.

The event featured international stars like Lady Gaga - who exhibited in a Moulin Rouge-style performance singing "Mon Truc En Plumes" - as well as Celine Dion, who returned to the scenes after four years, signing an emotional rendition of Edith Piaf's "l'Hymne à l'Amour" from the Eiffel Tower.
