Jennifer Hudson, 30, has lost a lot of weight since her "American Idol" days. These days she is much more confident with her trim and fit figure. However, she still receives criticism despite her weight loss. Jennifer said people have made comments like "You're going to gain the weight back" and "You lost too much weight." The beautiful singer doesn't let the harsh comments phase her though. She keeps her body in shape for herself and doesn't pay attention to the negative comments.

Jennifer isn't the only celebrity who has lost weight in recent years. Here are some others:

Snooki

Nicole "Snooki" Polizzi is no stranger to negative comments about her weight. Many people have criticized the "Jersey Store" star for being too heavy for her 4'9" frame. When she was in high school, she suffered from an eating disorder, so the mean comments probably got to her. The bronzed babe has lost about 20 lbs and is enjoying her new slim body. Luckily, she lost it the healthy way this time. Instead of starving herself, she started to eat healthier and go to the gym more.

Jordin Sparks

Jordin Sparks follows in Hudson's footsteps by dropping some weight after being on "American Idol." Jordin used to be a size 14 and is now a svelte size 8. The 22-year-old felt so confident about her new body that she posed in a bikini for People Magazine. The "American Idol" winner lost the weight by controlling her portion sizes and taking Zumba classes.

Drew Carey

We all remember Drew Carey, 53, as the chubby, funny guy who starred on "The Drew Carey Show." Even though we can still think of him as the funny guy, we can no longer consider him chubby. The "Price is Right" host lost about 80 lbs a couple of years ago. He said he lost the weight because he was tired of looking fat on camera. Drew lost the weight by sticking to a low-carb diet and exercising rigorously at the gym.

Kelly Osbourne

Kelly Osbourne, 27, admitted that the harsh criticism she received about her weight in the press crushed her self-esteem. The reality star even said that she believes it was the main reason she ended up in rehab three times. One day, she stopped feeling sorry for herself and started to work out at the gym regularly and eat healthy foods. Kelly ended up dropping 50 lbs off her 5'2" frame a couple of years ago. She finally felt comfortable in her own skin and posed in a bathing suit for Shape.

Jonah Hill

Jonah Hill, 28, was almost unrecognizable when he lost weight last year. He was no longer the hefty guy we remembered from "Superbad" and "Knocked Up." When asked about his weight loss, he joked, "I just woke up one day and was like this." It would be great if it was really that simple! Jonah actually went to see a nutritionist and started taking his health seriously.
