Robert Pattinson Hair Dos and Don'ts: 'Twilight' Actor Turns 27 (PHOTOS)


When we think of "Twilight" hottie Robert Pattinson, one thing comes to mind: No, not his sexy British accent or his piercing blue eyes, but his gorgeous full head of hair!

Kristen Stewart's boyfriend turns 27 years old on May 13 and as far as we know, he isn't losing his precious locks.

The Brit has had many different hairstyles since he first burst onto the scene (and into our dreams) as vampire Edward Cullen in the mega-hit movie franchise, "Twilight," although he and Kristen love to hide their heads underneath baseball caps whenever the paparazzi are around. (Show us your pretty faces, RPatz and KStew!)

From tousled to cropped and messy to buzzed, Pattinson has changed his hair more times than he's made movies. But not every hairstyle has made us quiver with lust. In fact, it seems as if Rob styles his hair to deliberately look less attractive (see his half shaved head at the 2011 San Diego Comic-Con.)

So, to celebrate RPatz's 27th birthday, we take a look at hair dos and don'ts, courtesy of our favourite movie vampire.
