Jennifer Hudson has changed a lot since she broke out with a big Oscar win in 2007. And after seeing her on the red carpet Sunday [Feb. 24] night, just had to go back and check out the pictures from her Oscar appearance six years ago.
Jennifer's weight loss has been pretty remarkable, and she's been open about her work with Weight Watchers to slim down. In 2007 she won an Oscar for Best Supporting Actress for her work in Dreamgirls and on Sunday she revisited the Academy Awards to sing a number from the movie in a tribute to musicals. Check out her 2007 and 2013 photos above.
