Singers, sports stars, actors and other celebrities just seem to be getting younger and younger. These days if you haven’t made it to the big time before you turn 21, you might feel over the hill. Those who do hit the big time can earn so much money and live the high life that it must be tough to pick 21st birthday gifts for them – well, tough unless you read our guide to what to get them.

Stars who’ll be getting 21st birthday gifts in 2008:

Hilary Duff (28 September): The Lizzie McGuire actress is now embarking on a singing career. She won’t need a recording studio session bought for her, but if she wants to aim for the retro market, perhaps she’d like a 21st Birthday Classic Years CD & Greeting Card – a CD of songs from the year she was born, 1987.

Chanelle Hayes (11 November): The Big Brother contestant clearly wanted to be a celebrity, but she’s not appeared on many magazine covers lately. Perhaps her friends could console her by including a delux glamour makeover session among her 21st birthday gifts.
