We learned so much this week we can barely cope, but we'll give it a go sharing it. Starting with this... Arcade Fire will headline Glastonbury on the Friday night (June 27). The band announced they'll be heading to Worthy Farm via a Twitter picture of their tour date (written in chalk, obvs) and a cryptic post saying "Next year, one week in June".
When Dev Hynes' lost all his possessions and his puppy Cupid in a flat fire, we discovered the generosity of fans. More than $24,302 (£14,835) was donated to a fund set up by his girlfriend's mum. He says he's donating it to three charities. "Imagine being outside of your home one day," wrote Dev in a blog. "Then somebody presses delete, on the last decade of your life."
Former N-Dubz member Fazer has declared bankruptcy. Filing for the status on December 4, he seems unfazed by his financial insecurity, focussing on the more important things in life. "How's is EVERYWHERE sold out of them little furby things," he tweeted today.
Tulisa Contostavlos has denied, in court, charges she played a part in the supply of Class A drugs. She was arrested after a tabloid newspaper report claimed she was involved in an $860 cocaine deal. Forced to reveal her address during the hearing, she said "I might have to move to a new address" with her solicitor saying it might attract "unwanted visitors".
If we weren't sure already, we learned you should never piss off Angel Haze this week - even if you're a major record label. When Island Records pushed back her album 'Dirty Gold' to next summer, Angel leaked the LP online as a massive "fuck you".
Pussy Riot members Nadya Tolokonnikova and Maria Alekhina are going to be freed three months before their scheduled release date. The pair were arrested for performing their now infamous 'Punk Prayer' anti-Putin protest in February 2012.
Justin Bieber left us all excited when he said he was "retiring" from music in an interview with an LA radio station. "The new album... I'm actually retiring," he said. "I'm retiring man. I'm just gonna take some time. I think I'm probably going to quit music." Unfortunately, it turns out he was joking.
Adele got the giggles while accepting her MBE from Prince Charles. She visited Buckingham Palace to collect the award on Thursday alongside PJ Harvey and described it as a "very posh" affair.
James Arthur's admitted he's "been an idiot", blaming homophobic comments made in a rap battle against MC Worthless on "ego" and "foolish, foolish pride". "All my confidence has disappeared because the whole nation thinks I'm a homophobe who looks like a monster," he said.
Who needs build-up hype? After unexpectedly releasing her fifth studio album last Friday, Beyonce taught us the power of social media this week. Having already reached Number 1 in 104 countries and selling more than a million copies worldwide, it's now the fastest-selling album ever on the iTunes Store.
And, the biggest tour of the year was… Bon Jovi's?! The rockers played to more than two million fans across 90 shows in 2013, grossing $205m (£125m). Their gigs made more money than Beyonce's, One Direction's, Bieber's and The Rolling Stones'.
We discovered Wayne Coyne rates Miley Cyrus' 'aesthetic' over Lady Gaga's. He revealed he wasn't a fan of Gaga's "take me serious" attitude and preferred Miley's "I don't give a fuck" vibe. "I really like that thing where the people are inside the rainbow and they walk around," he said. That explains the time he planned on releasing a collab album with Ke$ha…
The Velvet Underground drummer Moe Tucker has said she misses frontman Lou Reed "a hell of a lot". Paying tribute to her former bandmate, who passed away aged 71 in October, she's revealed the pair had a brother-sister relationship. "Now Andy [Warhol]'s gone, Sterling [Morrison]'s gone, Nico's gone and Lou's gone," she said. "It feels strange. I miss them all, but I really miss Lou."
Finally we learned that Kanye West will never stop playing is music, even on a movie set. Will Ferrell described Yeezy's Anchorman 2' cameo as "surreal" in an interview on The Jonathan Ross Show. "He was playing the new tracks a lot - over and over. Even when you're trying to film, he's playing the tracks," he joked.
Ian Watkins referred to charges of child sex abuse as "megalolz" in a prison phone call, a court heard this week. The former Lostprophets frontman has been sentenced to 35 years in prison.
