It's the smack seen around the world.
An overzealous fan got a little too close to Rihanna at her concert in Birmingham, England, on Monday night. While singing "We Found Love," the songstress decided to walk down by the front row, only to have someone tug on her outfit. Ri-Ri quickly turned and struck at the person with her microphone and walked away.
But the Barbadian beauty isn't the only singer whose fans can get a little too close for comfort during their shows.
Here, we give you six more reasons why our fave superstars need so much security...
1. Beyoncé: A male fan of the singer became a bit overzealous during her concert in Copenhagen, Denmark, and proceeded to slap Bey's butt as she walked down to the front of the stage while performing "Irreplaceable."
2. Justin Bieber: The pop star was in the middle of a concert in Dubai last month when a young man rushed the stage. In an attempt to grab the Biebster, the fan knocked over a piano. A shaken Bieber finished the show after a quick three-minute break.
3. One Direction: A 14-year-old threw her shoe onstage during a 1D concert in February in Glasglow and hit Harry Styles smack in the middle of his groin. She was quickly thrown out of the arena, but Styles apparently intervened to get her back in.
4. Miley Cyrus: It was about two years ago when a fan rushed onto the stage to hug Cyrus after she sang "The Climb" during a concert in Melbourne. "Oh, my God," Cyrus said before a stagehand quickly rushed her backstage.
5. Britney Spears: A 20-year-old man walked onto the stage at the Mohegan Sun in Connecticut to try to dance with the pop princess during her encore performance of "Womanizer." Brit-Brit screamed when she saw him, but continued performing while her dancers and security yanked the dude off the stage.
6. Demi Lovato: The X Factor judge encouraged her fans get closer to the stage during a Paraguay show, but the plan imploded when one gal jumped up and gave her a bear hug. After being taken backstage, Lovato returned but told the crowd, "You gotta chill out." Ya think?
