Kate Hudson is trading red-carpet polish for Midwest grit. The 46-year-old actress told W Magazine she happily gained weight and ditched beauty rituals to portray Claire Sardina, front-woman of the Neil Diamond tribute band Lightning & Thunder, in Song Sung Blue.
The Physical Shift
Hudson embraced a relaxed approach during the holiday shoot. “I put on 15 pounds, just to be nice and soft,” she said, adding that she also “stayed away from skincare routines” to feel authentic. The extra weight and bare-face look helped her channel Claire’s down-to-earth stage presence.

Before cameras rolled, Hudson and co-star Hugh Jackman hit the studio to record every Neil Diamond track used in the film. Jackman noted her calm demeanor, saying, “You seemed very at home” while he was the nervous one.
