Besides the Frankenstein-like Heidi Montag, the biggest body transformation of the year would have to go to Jennifer Hudson, which makes her the perfect cover girl for InStyle's annual Makeover issue.

On the cover of the magazine, the shrinking songstress -- who credits her dramatic downsizing to Weight Watchers -- shows off her new figure in one of the most body-conscious frocks on the market: a Hervé Léger bandage dress in vibrant purple.

On the inside pages, the new mother strikes an almost identical pose in a sporty, navy blue second-skin dress paired with a brown leather belt.

"I don't want to lose any more weight," Hudson assures her curve-loving fans, "and you're never going to see me skinny. I think this is a good, natural size for me. David [Otunga, Hudson's fiancé] doesn't like change. He tells me I have no breasts anymore. He tries to feed me. He's adjusting."

After making over her body, Hudson is also considering taking things a step further.

"I'm actually thinking about shaving my head," she tells InStyle. "I am! Because I feel I've got a good structure now [gingerly feels cheekbones]. My cousin's a beautician, and she always tells me, 'You could wear any hairdo.' So I'm thinking, What if I shave my hair? Not completely off, but low. I think that would be so hot. With my diamond studs? But with a cut like that, your face has to be made up at all times. It has to be on."

Watch your back, Rihanna!
