They're both from Long Island ... they're both terrible drivers ... and now Lindsay Lohan and Billy Joel have something else in common ... his lyrics tattooed on her body -- and TMZ has the photo.

LiLo rolled over to her favorite L.A. tattoo shop -- Shamrock Tattoos -- this week and got the words "Clear as a crystal, sharp as a knife I feel like I'm in the prime of my life" inked on her rib cage.

For those who weren't around during the "Storm Front" years -- the lyrics are from Joel's 1989 song, "I Go to Extremes." Pretty good song ... doesn't hold a candle to "We Didn't Start The Fire" though.

We're told Lindsay felt the lyric was important to her because "It represented where she is in life and everything she's been through ... it signifies that she's focused."

Rebecca Black I'm Not a Singer I'm a BIKINI Model

There is a MAJOR Rebecca Black crisis on Facebook -- with allegations of deception, identity theft ... and most importantly a smoking hot bikini model ... who happens to be named Rebecca Black.

Turns out, there's more than one person on Earth named Rebecca Black -- one of whom is a self-described, "fitness bikini competitor." And she has the photos to prove it.

Black (bikini) tells TMZ ... sometime in the past week, her friend list on Facebook exploded from 800 friends to 73,000 ... and she had no idea how it happened. Black started getting emails from upset fans of the singer -- accusing her of intentionally hijacking the 14-year-old's page ... but Black (bikini) claims she never tried to steal anyone's identity.

Black (bikini) insists Facebook is to blame for somehow "merging" her account with Black's (singer) without her permission.

We called Facebook for comment -- so far no word back.

Still, there is a silver lining here ... check out the AWESOME bikini pics -- Fun. Fun. Fun. Fun. Fun.
