With the havoc wreaked by the pandemic, it's been a year most of us are happy to leave in the past.
And that's a sentiment also shared by many of the world's most famous faces, with a number of stars gladly bidding adieu to 2020 as the clock struck 12 on New Year's Eve.
From Taylor Swift and Reese Witherspoon to Hailey and Justin Bieber, and Chrissy Teigen and John Legend, here's how the world's celebrities said hello to 2021.
Queen Elizabeth II
The British monarch posted an uplifting message to mark the end of 2020, along with several shots taken throughout the year. Alongside photos of the Queen and Prince Philip marking their wedding anniversary, and the knighting of Captain Sir Tom Moore, the royal wrote: "We should take comfort that while we may have more still to endure, better days will return: we will be with our friends again; we will be with our families again; we will meet again.”
Cristiano Ronaldo
The Portuguese footballer rang in the new year with his four children and his partner, Georgina Rodriguez. The family marked the occasion by decorating their home with balloons, including four that together read "2021".
"2020 was not an easy year, there’s no doubt about it," Ronaldo captioned the shot. "But now it’s time to bounce back and show that, together, we can make a difference. Because no matter how hard is the fall, what really defines us is the way we get back on our feet and how fast we are ready to face new obstacles."
Kourtney Kardashian
The reality TV star got dressed up for the occasion, even though she stayed home to watch the clock strike 12.
