(Cover) - EN Star Style - Reese Witherspoon thinks she looks funny unless she pencils in her eyebrows.

The 34-year-old Hollywood actress often has to alter her appearance for movie roles, and admits a recent part required her to change the colour of her eyebrows.

The fair-haired star doesnt like the shade of her new brows, and requires the assistance of a pencil before she feels comfortable with them.

I recently dyed my eyebrows on a movie, so I have to pencil them in. Its a pain but they look funny if I dont. Dont ever dye your eyebrows! she laughed in an interview with the British edition of Glamour.

Reese also shared some of her top beauty tips with the magazine. Known for her fresh-faced appearance, the gorgeous star says her secret to a wide-eyed look comes with the help of white eyeliner.

Putting a little white eyeliner in the centre of your inner eye when youre tired makes your eyes look awake! she explained. (C) Cover Media
