Some celebs stick with a signature look for basically their whole careers (Whoopi Goldberg, Diane Keaton, etc), but most red carpet walkers like to change up their appearance every now and then, at least every couple years or so.  Then there’s that special group of celebs who make drastic hairstyle changes that make you do a double-take to make sure that’s really the same person.

Check out our gallery of celebs who can morph into  different beings in the blink of an eye…or at least as long as it takes to attach a lacefront wig or a sew-in.

Rapper/Dancer/Reality Show Judge Lil Mama constantly changes up her look.  Here she goes from an ’80s hip hop throwback to a college kid/incense burner.

Keyshia Cole came on the scene full of Oaktown attitude with blazing red hair, but as she shows here, she can also do the sophisticated evening looks too.

More than a few times Da Brat has shown the world that she is more than baggy jeans and braids.

Kelly Rowland goes from ’70s vixen to sweet innocent girl next door in these pictures.

You never know what Erykah Badu will have on her head or what will come out of her mouth. Don’t you just love her?

First Lady Michelle Obama generally sticks to her voluminous, layered bob, but sometimes she switches it up with a slicked back do. Nice!
