Things got very crazy at a Beyoncé and Jay Z concert on Saturday at the Rose Bowl stadium when a 25-year-old man bit off the finger of another man. Yup, you read that right. According to a local newspaper, Robert Alcaraz Garnica allegedly groped a woman at the "On The Run" concert and chaos ensued. 

Of course the woman's boyfriend was not pleased with the groping and confronted Garnica. The two reportedly started fighting and Garnica bit the man's finger, severing the tip. The 25-year-old was arrested on suspicion of sexual battery and mayhem and the unidentified boyfriend was taken to a nearby hospital.

"During the altercation, the suspect bit the victim, causing serious injury to his finger," Pasadena police Lt. John Luna told the Pasadena Star-News. "He lost the tip of one of his fingers."

According to TMZ, which obtained very graphic photos of the man's severed finger, the boyfriend plans on suing Garnica. Pasadena Star-News reports that the finger-biting wasn't the only incident at the Rose Bowl that night, police arrested eight concertgoers for public drunkenness and two were arrested for scalping tickets.

The second night Beyoncé and Jay Z returned to the Rose Bowl for a show, everything went a lot more smoothly. There was even a bunch of celebrities in attendance including Natalie Portman, David and Victoria Beckham, Salma Hayek, Courtney Love and Nicole Richie.

The "Diva" singer and her rapper husband have been making headlines a lot lately but not for their sold-out shows. The couple has been the subject of endless divorce rumors, with one report claiming that Beyoncé and Jay Z will split after the tour is over.

A recent report by the New York Post's Page Six said sources connected to the couple are worried Bey and Jay might cancel the tour because of their marital issues.
