Entertainment buzz: Facebook's top 10 moments of the week

There was a lot of must-see TV happening this week, from another jaw-dropper on "Game of Thrones" to a heated "Real Housewives of Atlanta" reunion that included a highly-publicized brawl between cast members.

Speaking of heated exchanges, there was another one between George Clooney and casino mogul Steve Wynn about President Obama that got people talking, and buzz is building ahead of Godzilla's latest trip to the big screen.

Facebook has tallied the top 10 buzziest stories in entertainment this week, and all of those topics made the most-talked-about list. What had you talking? See what you missed in this exclusive list on CBSNews.com.

1. Bravo's "The Real Housewives of Atlanta" brawl on Sunday's reunion special

The first part of "The Real Housewives of Atlanta" reunion -- which featured the much-talked-about fight between cast members Porsha Williams and Kenya Moore -- aired Sunday night on Bravo. Williams was arrested on a simple battery charge following the brawl, and Moore has said she's seriously considering leaving the show after what happened.

The stars are expected to chat about the brawl on Tuesday's episode of "The View."

2. "The Boondocks" kicks off its final season on Cartoon Network

"The Boondocks" earned its highest-ratings ever when it returned for its final season on Monday night. The Adult Swim animated series, which had been off the air since 2010, is back now, but without the involvement of creator Aaron McGruder. The premiere episode earned 1.4 million viewers among adults ages 18-34, beating out "The Voice," the NBA playoffs and "The Blacklist" for the night's top spot in that demographic.

3. Controversial scene in HBO's "Game of Thrones"

Skip over this one if you're not up to date on "Game of Thrones." Those who did see this week's episode, "Breaker of Chains," were probably shocked to see Jaime Lannister force himself on his sister, Cersei, while they were next to the corpse of their murdered son, Joffrey. Some viewers raised objections over the scene, particularly because in the books the series is based on the sex (while still incestuous) is consensual.

Author George R. R. Martin addressed the controversy on his blog, writing, "The scene was always intended to be disturbing... but I do regret if it has disturbed people for the wrong reasons."

4. Actor George Clooney and hotel tycoon Steve Wynn get into spat over politics

George Clooney and casino mogul Steve Wynn are not backing down after an angry exchange earlier this month. The showdown, which took place inside Wynn's $2 billion resort in Las Vegas, happened while he was having dinner with the actor and seven other people at a high-end steakhouse and the conversation turned to President Obama. But what happened in Vegas hasn't stayed there -- the two men have shared separate, candid accounts of what they say happened.

5. DJ Deadmau5 addresses "Arcade Fire" frontman Win Butler's recent comments about EDM musicians

A war of words between Arcade Fire's Win Butler and Deadmau5 began at the first weekend of Coachella, when Butler said, "Shout out to all the bands still playing actual instruments at this festival." The DJ wasn't too pleased to hear that jab at EDM musicians and fired back in a series of messages on Twitter.

"[Expletive] to remember: A computer is a tool, not an instrument," he wrote. " Arcade Fire needs to settle down. Some dudes devote their lives to instruments, others to electronic composition by CPU... If I wanna watch real artists perform, I'd pick the opera before wasting a [expletive] minute of my life with Arcade Fire."

6. Anticipation for the upcoming "Godzilla" movie

Godzilla will be causing monstrous chaos and destruction on the big screen once again when a new reboot starring Bryan Cranston, Elizabeth Olsen and Aaron Taylor-Johnson hits theaters May 16.

Andrew Stewart of Variety told CBS News the film could be a potential blockbuster. "That property hasn't necessarily done so well in the past -- but they're taking a more realistic approach this time around -- less stylized. I think that can help it. Certainly with the success of 'Batman' and 'Man of Steel' --that sort of realistic story-telling," he said. "I think audiences have come to appreciate and respond well to that...It certainly cost a lot and has a lot riding on it."

Harris, who received criticism for both his rock and country performances, was the one sent home the following night.

8. "Tyler Perry's Madea's Neighbors From Hell: The Play" released on DVD

Everyone's favorite "Southern mama" returns in a new stage play from Tyler Perry, featuring Madea and Aunt Bam going up against some troubled new neighbors. The production was performed in front of an audience in Atlanta, but you can watch it from anywhere now that it's been released on DVD.

9. Actress Lupita Nyong'o chosen as People magazine's "Most Beautiful" person

It's been a big year for Lupita Nyong'o. Not only did she win an Oscar for her breakout role in "12 Years a Slave," but the 31-year-old actress has also been named "Most Beautiful" by People magazine. "It was exciting and just a major, major compliment," she said. "I was happy for all the girls who would see me on [it] and feel a little more seen."
