Nicola Roberts is planning to head back to college to study beauty ahead of the launch of her new range of Dainty Doll cosmetics, which is due out next year. The Girls Aloud star first launched the collection for fun as a result of the TV show The Passions Of Girls Aloud. But the cosmetics line has done so well she’s now keen to turn it into a proper business, and wants to make sure she’s completely clued up on the best beauty ingredients to use. Okay, so some may argue it may have best if she’d done that to start with, but we still reckon it’s commendable that she’s getting so involved in the products she’s putting her name when do many celebs don’t bother - we have a funny feeling that Paris’s Chihuahua didn’t actually write The Tinkerbell Hilton Diaries: My Life Tailing Paris Hilton.
