Although the pair are notoriously private about their relationship, insiders told PEOPLE that the couple is betrothed.
The National Treasure star and the 52-year-old met in 2015 when they were filming Sky. They went public with their relationship in March 2017.
A year later, pregnancy rumors circulated in May 2018. Their daughter was reportedly born in November of that year but they never shared her name or date of birth.
The private couple occasionally gives fans a glimpse into family life. In July, The Walking Dead star shared a photo where he carried his daughter on his shoulders while on a walk with Kruger. The doting father made sure to keep her face hidden from view.
"She’s not really girlie, she’s kind of a dude," the 45-year-old actress previously told PEOPLE of her daughter. "It’s fun to have a girl, I will say."
"He just looks at her with unconditional love," she gushed of Reedus' relationship with their daughter. "I wish he would look at me like that."
Reedus also shares 21-year-old son, Mingus, with ex Helena Christensen. "He’s great! You know 19 years is a big gap so he’s really like stepping up to be this protective big brother," Kruger said of her daughter's big brother.
The blonde beauty previously opened up about welcoming her first child at 42. "I didn’t think I wanted children for a long time. I was too selfish," she previously told PorterEdit. "But by the time I got to about 35, I thought, yes, I probably do want one. But then you have to wait for the right person to come along."
Reps for the Welcome to Marwen star and Reedus did not provide a comment to PEOPLE.
