Jack is currently starring in the TV dance show, which is the US version of Strictly Come Dancing, and Lisa is definitely his No1 fan.
Joining her hubby backstage last night (28 October), Lisa cuddled up to Jack as they posed for a picture together in the dressing room.
Jack, who is partnered with professional dancer Cheryl Burke on the show, had his hair styled all ready for the dance floor.
Lisa, meanwhile, looked gorgeous in a pretty black top with cutout detail around the neckline. She completed her look with a slick of bright pink lipstick.
Sharing the picture on Twitter, Jack told his followers: "Pre-show pic with my lady @MrsLisaOsbourne! #DWTS."
