Monaco will appear after hockey player Danny (played by Derek Theler) is offered a cameo on GH. His crush Riley (played by Chelsea Kane), a GH super-fan, will come along for the trip and lose her cool around Monaco.
Monaco isn't the first GH actor to visit Baby Daddy. Antonio Sabato Jr. (ex-Jagger Cates, GH; ex-Dante Damiano, The Bold and the Beautiful) appeared as Gerard on the show in 2013. Baby Daddy isn't the only show the two have in common. Sabato will be starring in season 19 of Dancing With the Stars, where Monaco won the first season of the show and finished third in the show's All-Star season.
In Port Charles, Monaco's Sam is in the midst of what might be a budding romance with Patrick Drake. However, that situation is sure to get complicated with the news that Billy Miller (ex-Billy Abbott, The Young and the Restless; ex-Richie Novak, All My Children) will be joining GH as Sam's presumed-dead husband, Jason Morgan.
Entertainment Weekly first reported the news of the crossover.
