Jennifer Hudson arrived at LAX with a big smile and her son David Otunga Jr. yesterday. She was in town to attend the Grammys, where she wowed in Versace on the red carpet and took the stage with Christina Aguilera to do a tribute to Aretha Franklin. Jennifer also made a stop by The Ellen DeGeneres Show and headed to Malibu for a photo shoot during her stay on the West Coast. She's out promoting her new single "Where You At" ahead her full album's release in March, though the singer also has her dramatic weight to flaunt. She told Oprah during a recent appearance that she lost 80 pounds, and it's clear that Jennifer is loving her body transformation!
