With Memorial Day having opened the week, the work on the Newsroom Blog this week was slightly more abbreviated than usual. But that doesn't mean that the coverage wasn't fast, furious, hot and heavy day-in and day-out. So before you head to Atlantic City to check out the opening date of Kings of Leon's latest tour, stand in line for your third screening of "Marmaduke" or experiment with making ceviche, scroll down and catch up with all the action you might have missed. It's a nice cross-section of greatness, featuring the music world's lamest feud, hip-hop's craziest collaborations and the what is probably the first time you've seen T.A.T.U. referenced in half a decade.
» The MTV News 2010 Summer Songs Poll closed earlier this week, with Lady Gaga's "Alejandro" standing tall at the end. She was so excited about the win — which was driven by her passionate flock of fans — that she tweeted about the victory.
» The strange exchange of words between international pop genius M.I.A. and New York Times writer Lynn Hirschberg came to its apparent conclusion, but not before a formal correction and a dis track. It shot straight to the top of the charts as one of the lamest music-related feuds in history.
» Justin Bieber premiered another new video this week, this time for "Never Say Never," his tag-team with Jaden Smith that appears on the soundtrack to the upcoming film "The Karate Kid." It's a fun clip, but it doesn't hold a candle to that "You're the Best Around" montage.
» Also in Justin Bieber news: He performed a free show live in Rockefeller Center in New York and attracted some extremely devoted fans.
» "American Idol" runner-up Crystal Bowersox stopped by the MTV Newsroom to talk about her experience on the show, what her album might sound like and her former life as a person who sold ice cream out of a cart.
» The auditions for the new season of "So You Think You Can Dance" chugged along, this time with an awful lot of back flips.
» Taylor Swift is selling out stadiums and spending 13 straight hours with fans (because 13 is her lucky number, you see), which means that she better get cracking on perfecting the flux capacitor if she hopes to continue kicking it up a notch.
» We celebrated the debut of Avril Lavigne's first album Let Go and reminded you that "Complicated" is way, way better than you probably remember it being.
» Another track from Eminem's new album Recovery leaked, which meant that we got to hear what it sounded like when Slim Shady and Pink team up. As it turns out, it's history-making.
» The planned Michael Jackson museum may (or may not) be getting started soon. It's a great idea, but it just made us long for a proper Kurt Cobain memorial.
» Miley Cyrus kissed a girl (no word on whether she liked it or not) and joined Madonna & Britney, Neve & Denise and Willow & Tara on the list of the best girl-on-girl kisses in pop culture history.
» Finally, just remember that there are some girls in Arkansas who accidentally saw Kris Allen in the nude when he was 17. No, really, he told us.
