Alongside the caption, Amell posted a photo of himself holding Mavi as they watched an episode of The CW's The Tomorrow People, a new series which his younger brother Robbie Amell stars in, on television from inside the couple's hospital room.
"I'm excited -- no I'm not excited, I'm very excited!" Amell told Us at the time. "I'm sure that nervous energy will accompany that eventually, but only in a positive way."
Added Jean, "I haven't had any cravings, but [Stephen's] been great."
The couple wed on Christmas Day in the Caribbean in 2012.
Jean quitAmerica's Next Top Model in the fifth edition's fourth episode because she was disapproving of her makeover, which changed her long brown locks to a super short blonde hairdo.
Creator and judge Tyra Banks hoped to cut even more of her hair off once she saw the results, but Jean left the show before letting that happen.
