'The Body Coach' Joe Wicks has revealed his newborn son's name.

The 33-year-old and his wife, Rosie, recently revealed that they had welcomed their second child - three weeks before his due date. And on Friday, Wicks gave fans an update on the little one as he shared that they had decided on a name for him.   "We’ve finally decided on a name for our little boy. His name is Marley," the dad-of-two added. "He’s been in the hospital for a week now with an infection but he’s on the mend and getting stronger each day." He added that the hospital staff have been "wonderful" and "so loving" to Marley and Rosie every day. "This is the first time he’s properly opened his eyes and he’s just so chilled and relaxed even though he probably feels rough," he continued. "Welcome to the world my little boy Marley." Wicks previously shared a series of snaps of the moment that their daughter, Indie, met her newborn baby brother. The fitness guru told his Instagram followers back in August that he and Rosie were expecting their second child. "Weeeeeee’re having another baby," wrote Wicks. "We are very happy and excited to grow our family. We don’t know the sex and won’t find out but Rosie is now 19 weeks pregnant so Indie will be getting a little brother or sister in January."
