Overnight sensation Rebecca Black is having the time of her life. Her music video is at over 38 million views on YouTube, she's making $27,000 a week from the sale of her single, and last night, she went on The Tonight Show with Jay Leno.

The 13-year-old viral stars says that that Nicole Richie, Simon Cowell, Willow Smith and Ryan Seacrest are fans. Lady Gaga even called her a "genius".

Unfortunately, she didn't really sing when she got the chance. Watch the interview and "performance" above.
