The war between smartphone manufacturers continues. After consumers complained that Apple’s new iPhone 6 Plus has a tendency to bend when kept in a pocket for a long time, Samsung tested out the Galaxy Note 4 — on a robot butt wearing jeans.

A new Samsung ad shows a series of pressure tests on the Galaxy Note 4, a phone that’s even bigger than the biggest iPhone ever released. The most ridiculous test apparently simulates a 220-pound man sitting directly on the phone a hundred times in a row. According to Samsung, the Galaxy survived the robot butt challenge just fine.

Apple has a history of suing competitors like Samsung over similarities between products, so maybe they deserve the subtle mockery by way of robot booty. Either way, it brings a whole new meaning to the phrase “apple bottom jeans.”

Watch Samsung troll Apple in the new ad below.

She might not be known as a sports expert yet, but Katy Perry made a convincing guest picker on ESPN’s “College GameDay” show earlier today (October 4). The “Roar” singer gave her hilarious picks for upcoming college football games alongside seasoned sports broadcasters.

Wearing a fuzzy pink sports jersey and bright red and black hair, Perry wasn’t shy about picking her teams based on which ones had the cutest players. When asked whether she’d pick TCU or Oklahoma, she chose Oklahoma, saying, “I’m picking this one based one on… looks. Trevor Knight, do you hear me?”

The singer pulled a few more gags before her screen time was up, including ripping a mascot’s head off and throwing corn dogs at the camera.

Watch highlights from Katy Perry’s guest spot on “College GameDay” below.

Lorde has been having a great time in California. Last night (October 3), the New Zealand singer posted pictures of an amazing piece of fan art painted by a boy named Fabian from Berkeley.

Ella Yelich-O’Connor, the 17-year-old pop star who dominated the charts last year with her single “Royals,” shared photos of the painting with her fans on Twitter a day after her concert at Berkeley’s Greek Theatre. She even took a few selfies next to the work of art — and the likeness is pretty uncanny!

The teen star will continue her North American tour with three more dates in California before she plays one last show at Austin City Limits on October 12. She also took the time to thank all her fans that make gifts for her:

Last Monday (September 29), Lorde dropped a new single, “Yellow Flicker Beat,” from the soundtrack she’s curating for the next “Hunger Games” movie, “Mockingjay Part 1″. Listen to the fiery new track below.

Coldplay‘s Chris Martin made a surprise appearance at the Hollywood Bowl last night (October 3) as he joined Kings of Leon onstage for two songs of their L.A. concert.

The Nashville rock band had already played through most of the second-to-last concert on the U.S. leg of their Mechanical Bull tour when they surprised their audience by inviting Martin onstage.

Martin played piano and sang on “Talihina Sky”, a hidden track from Kings of Leon’s 2003 debut album Youth and Young Manhood that they rarely play live. He also played on “Notion,” the chart-topping single from the 2009 album Only By the Night.

This was very amazing #chrismartin #kingsofleon #hollywoodbowl #fridaynight

Martin’s new girlfriend Jennifer Lawrence, who he recently started dating after his split from his wife, actress Gwyneth Paltrow, was apparently in attendance backstage. The 24-year-old “Hunger Games” star has reportedly also been spotted hanging out with her BF at rehearsals . Last month, she sat in the balcony for Coldplay’s concert at the Ace Hotel in L.A. She may be joining the band on the forthcoming tour to support their new album, Ghost Stories.

This isn’t the first time that Martin has joined Kings of Leon onstage. Their friendship apparently started in March, when the Coldplay frontman took the stage during Kings of Leon’s set at Radio One’s One Big Weekend in Glasgow. The impromptu rock supergroup played “Fans” together.

Yelena Serova just became the first Russian woman to fly up to the International Space Station on Friday (September 28), but not before she was subjected to some good old-fashioned sexism.

During a news conference before her launch into space, reporters asked the cosmonaut how she was planning on doing her hair and makeup in zero gravity. Mysteriously, the media didn’t ask any of the male astronauts similar questions. Serova was quick to point out the double standard.

“Can I ask a question, too? Aren’t you interested in the hair styles of my colleagues?” she said.

The 38-year-old engineer just became the fourth Russian woman ever to go into space. She’s spent the last seven years training for the mission, and she will work on the ISS with two male colleagues for the next six months. Yet the media still wants to hear about her eyeliner? C’mon guys!

Russia became the first country to send a woman into space back in 1963, when cosmonaut Valentina Tereshkova took off on an early mission during the space race. It’s good to see that Serova is continuing her country’s tradition — and not taking any flak from lazy reporters while she’s at it. Watch her rebuff the reporters below.

High school students near Denver, Colorado, are walking out of class, but not because they don’t want to learn.

Proposed changes to the Jefferson County school board’s AP US History curriculum, which would force teachers to emphasize patriotism and downplay civil unrest, have inspired nearly 1,000 students to stage walk-out protests demanding a fairer and more honest education.

Students started protesting earlier this month when word got out that members of the school board were reviewing the Advanced Placement U.S. History curriculum to make sure that it promotes “respect for authority” and patriotism without encouraging “civil disorder” or “disregard for the law.” By Thursday (September 25) they were on their fourth day of protesting.

“People think because we are teenagers, we don’t know things, but we are going home and looking things up,” said Savanna Barron, a senior at Lakewood High School, to the Denver Post. “If they don’t teach us civil disobedience, we will teach ourselves.”

A conservative majority recently won the election run the Jefferson County school board, and this is only one of the forms of protest that has erupted since then. Nearly 50 teachers called in sick or took a personal day recently to protest, and the Jefferson County Sheriff’s Office said they’re even investigating threats against school board member’s children.
