We all know the phrase, "Don't judge a book by its cover." That couldn't possibly be more true than when it comes to Jess Greenberg.

Jess is a 20-year-old from London who obviously has the looks. Anyone can see that. She's jaw-dropping gorgeous.

But would you ever believe that this bombshell can sing and play guitar ... really well?

She has more than 665,000 likes on her Facebook page and nearly a million subscribers on her YouTube channel, not to mention millions of views on her videos. And while many of her fans are likely visitors just to look at her, she has many more who are genuine fans of her incredible talents.

Jess has posted covers of all kinds of rock acts, from Led Zeppelin and Stevie Ray Vaughan, to AC/DC and Fleetwood Mac. And seriously y'all, they're all incredible.

Aaaaaand it doesn't hurt that she's nice to look at, too. But here are some of our favorite covers Jess has done.

Stevie Ray Vaughan: 'Pride & Joy'
