Kate Hudson has addressed the criticism from the son of the real-life couple she and Hugh Jackman portrayed in Song Sung Blue. "Honestly, I don't even know - out of respect for our filmmakers, I'm not the right person to speak to it," the actress, 46, said in an interview with The Hollywood Reporter published on Thursday, January 8. Hudson played Claire Sardina, while Jackman portrayed her husband, Mike Sardina, in the musical film. Claire and Mike performed in the Neil Diamond tribute band, Lightning & Thunder.
