Celeb: Heidi Montag

Fashion Line: Heidiwood for Anchor Blue

Qualifications: The Hills' villainess can't stop competing with ex-BFF Lauren Conrad. Our verdict? Stick to L.C.'s line. At least she has some style!

Celeb: Gwen Stefani (wearing L.A.M.B.)

Fashion Line: L.A.M.B.

Qualifications: The rockin' mom-to-be is a bona fide fashion icon. She launched L.A.M.B. in 2004 to rave reviews and has since expanded it to include fragrance, eyewear and accessories.

Celeb:Camilla Alves

Fashion Line: Muxo for Kitson

Qualifications: Matthew McConaughey's baby mama channeled her beach bum style into a line of boho bags. Her biggest fan? Matthew -- he's almost never seen without his brown leather murse by Camilla!

Celeb: Beth Ditto (singer for UK band Gossip)

Fashion Line: For Evans plus-size stores

Qualifications:Beth, known for flashing her flesh in wild outfits, turned down a line for Top Shop (the Brit chain that sells model Kate Moss' line) due to size "limits." But the singer will design clothes sized 14-32 for the UK chain Evans -- for a large $400,000 paycheck.
