Jennifer Hudson revealed on Oprah last week that she lost a whopping 80 pounds while on Weight Watchers. What she didn't add, was that her new svelte figure has caused her some, well, sleep deprivation.

"At night I can't even sleep because I can't wait to see what I am going to wear the next day," Hudson admits to CNN while at a the Fourth Annual Essence Black Women in Hollywood luncheon last Thursday.

Who can blame her? The Grammy-nominated singer went from a size 16 to a size 6 by last May, and then slipped down to a size 4 by December.

"It's like a brand new me," she tells Oprah during the show. "Sometimes I don't even recognize myself."

We can barely recognize her on the cover of her sophomore studio album, 'I Remember Me,' which hits stores March 22. The album boasts the mid-tempo single 'Where You At,' written by R&B crooner R. Kelly.
