Is "The Real Slim Shady" actually "Harry Potter" star Daniel Radcliffe?

According to the caption of a video uploaded Saturday by YouTube user Mia Anderson, the 25-year-old actor did his best to channel his inner Eminem in front of a lively karaoke crowd at Cameron's Pub in Half Moon Bay, California — some 50 minutes south of San Francisco and west of San Jose.

And while it's not known if Eminem now considers Radcliffe to be "The Real Slim Shady," Anderson's video does appear to show the real Radcliffe, who'd attended a Comic-Con event in San Diego the previous weekend.

In the video, the opening lyric of "May I have your attention please?" earns cheers from the crowd before the karaoke participant launches into the lyrically challenging and occasionally profane song that charted in 2000.

Radcliffe's girlfriend, actress Erin Darke, appears to be dancing beside the performer and shouting the choruses. Radcliffe and Darke met in 2012, when they were on the set of the movie "Kill Your Darlings."

But what if this video's star is not the real Radcliffe? Perhaps we can take solace in one of J.K. Rowling's most memorable "Harry Potter" quotes: "Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real?"
