The festive season has got underway in Rio de Janeiro in spectacular style.
The world's largest floating Christmas tree has been lit up in the heart of the city.
Over 100,000 people flocked to the lagoon to watch a six-minute fireworks show. It's become one of Rio's main tourist attractions.
This year, the decorations on the 85 metre-high structure have been based on the four seasons.
