Hilary Duff Becomes Baggy Bashful

Hilary Duff gets shy and musters up a weak grin while shopping at Dos Gallos furniture store in West Hollywood on Monday.

The 21-year-old Come Clean singer went casual with a loose grey sweater and rolled-up yellow sweats.

The Duffster has been heating it up this winter with her Maxim magazine layout and took time out last month to ring the bell at the New York Stock Exchange.
