In 2011, following Kang Ho-dong's retirement from the entertainment industry, Leeteuk and Boom took over as co-MCs of "Star King". From September to November, Leeteuk became a dad in "Hello Baby season 4" with girl group Sistar. Leeteuk also became part of MBC reality show "We Got Married", as a new on-screen couple, with actress Kang So-ra becoming his on-screen wife. As of the April 10, 2012 broadcast, following the change in MCs and the departure of Shindong from "Strong Heart", the show was re-vamped with Leeteuk and Eunhyuk billed as two of the 'six-fixed guests'.
