What HASN'T happened this year? From break-ups and make-ups, to the biggest tours and craziest viral trends, we're counting down some of the most memorable moments!
You may not have heard of her - she's a small-time recording artist, but Adele released one of the most powerful albums of the year. And made us get through a hell of a lot of tissues. Here come the feels.
If you tell us that - after 'Purpose' - you're not a fan of Justin Bieber's then we KNOW you're lying. We cannot stop dancing to 'Sorry', 'Lover Yourself', 'Where Are Ü Now' and 'What Do You Mean?'. Seriously. We can't stop! Someone get help! (Picture: Gobinder Jhitta)
The entire world applauded as the Olympian and reality star debuted her appearance on the cover of Vanity Fair earlier this year. Kinda trumped Kim's baby news, didn't it? Soz, Kimmy!
We can't even blame Ariana Grande for sticking her tongue straight on this plate of unsold donuts. They look almost as sweet as she does!
One thing you should probably remember is to not grab an incoming drone when performing live on stage. You will slice open several fingers and fracture your hand. Shame no-one told Enrique Iglesias!
You're not doing too bad when you release '679' AND collaborate with David Guetta in the same year. Who cares if we have to listen to his verse eight times just to work out what he's saying - they're catchy AF.
Your friends aren't half as cool as Taylor Swift's pals; Candice Swanepoel, Uzo Aduba, Karlie Kloss and Gigi Hadid, are they? And just in case you wanted to be even more envious, she'll bring them onstage during her '1989' World Tour. (Picture: Getty)
Drake's, erm, dance moves (?) sent the world into frenzy, and we've seen everyone parody them - from Bryan Cranston to The Simpsons. Even our own Roman Kemp had a Hotline Bling-off against Justin Bieber. Standard, really.
When you've got the world's biggest singers in the room, it would be rude not to have them put on an impromptu gig, wouldn't it? From Rita Ora to Tinie Tempah, SO many people have fought against one and other for THAT crown. Bring on next year's battle!
David Guetta. Justin Bieber. Little Mix. Jason Derulo. No biggie, but... We did have the world's BIGGEST stars performing for two nights at the O2 Arena this year. And it was SO awesome. Expect amazing vocals, awesome moves and... A hella lot of toplessness. (Picture: Gobinder Jhitta)
Why wouldn't you want to be a part of the Kardashian gang? They're living the dream. So when it looked like we could mimic the young Kylie, everyone took to it and plumped their lips to look exactly like her... And in some cases, NOTHING like here. Gulp. (Picture: Instagram)
We ALL expected some craziness from Kanye West's headlining set at this year's Glastonbury. We didn't, however, expect comedian Lee Nelson to actually appear on stage. And neither did the 'Gold Digger' rapper, by the looks of things. (Image: Getty)
During her revival at the BRITs, the 'Like A Virgin' singer strolled down the catwalk, climbed atop a podium and was dragged off the stage backwards. Oh wait. That last bit wasn't a part of the routine?! Oh... Awkward. (Picture: Getty)
To say there's been a few naked scandals this year is the understatement of 2015. But does it phase the celebs? Of course not. Bieber was actually relieved by how impressive he looked, Caroline Flack just cropped out naughty bits and Miley, well, she posted the nudes herself! (Picture: Fame Flyet)
What year doesn't have it's share of jaw-dropping moments? But the biggest one this year would have to be for Robin Thicke and Pharrell Williams, after they owed Marin Gaye a whopping - sit down for this - £4.8million. Sigh.
Mr West revealed at the VMAs that he will - pause for dramatic effect - be running for president. We actually think he might stand a chance against Donald Trump! (Plus, it's worth it just to say the 'Kanye West Wing'!)
We hadn't heard much from the BIGGEST SINGING SENSATION AROUND... Until she dropped a HUGE track with Naughty Boy. Who actually saw 'Runnin' (Lose It All)' coming? We definitely didn't. And now she's working with Coldplay? What a time to be alive. (Picture: Getty)
Carly Rae Jepsen's 'Call Me Maybe' was SO infectious. There was no way she could top that, right? RIGHT?! Of course she did, with a little help from Oscar-winner Tom Hanks and Justin Bieber. And we really, really, really, really like it.
Who else would 'S' be for?! SERIOUSLY?! Let's agree that it was THE year of the Shia. He was watching all of his own movies in one sitting, he was shouting at us from a green screen, he was ringing us from a call-centre in Liverpool. And we're not even mad.
Things got a little/HUGELY awkward in the music industry when Swifty and Minaj took to Twitter to argue over Nicki being snubbed for 'Feeling Myself'. It's all resolved now... We think. (Picture: Getty)
It's not like people to get really angry and say things they'll regret on the internet, is it? So it comes as a shock when we see SO many arguments on Twitter. Zayn and Louis fighting. Amber Rose and the Kardashians rowing. Drake and Meek Mill bickering. (We do kinda love it though!) (Picture: Instagram)
Here's what happened. And deep breath... Miley got called out by Minaj. Bieber cried. Taylor copied Kanye. Rebel Wilson stripped off. Jared Leto and Willow Smith had a magical moment. Did we miss anything?! Picture: PA
The Weeknd has EXPLODED onto the airwaves this year. He shot to fame after collaborating with Ariana Grande, but then took over the music industry with hits in 2015, like 'The Hills' and 'Can't Feel My Face'. (Picture: Getty)
She battled it out for weeks and came out on top - Louisa Johnson won the reality show under the mentoring of the one and only Rita Ora. And we're SO pleased for that - have you heard her performance of Adele's 'Hello'? Just. Wow.
As if it's not awesome enough that millions of people are watching them on a daily basis, we're now hearing them too! The likes of Troye Sivan, KSI and Joe Weller are all releasing AWESOME tunes that are climbing their way up the charts. And we certainly ain't gonna stop them anytime soon. (Picture: Instagram)
He... Sniffle. Why did he have to go and ditch the boys?! It hurt us, but it's good to see Zayn Malik is making his own career, having departed from One Direction. We wish him all the luck... Not that he needs it with THAT facial hair. Phwoar.
