David Mengon is divorced from Willow’s mother, Sarah Mengon, who is now engaged to Lenox.
Lenox said David Mengon, who lives in Las Cruces, New Mexico, stays on the family couch when he visits, KXXV reported.
"He is not an outsider, he is and will always be apart of my life for the simple fact that we share the same daughter," Lenox told the television station.
The photographs were taken by Sarah Mengon, who owns Willie + Rose Photography, and the Facebook post has been shared more than 129,000 times since Saturday.
"You know, in the back of my head I thought this is something that should be shared but to the sheer volume it reached, no, we never in a million years thought it would go that far," Lenox told KWTX.
“I love these two guys so much. They’re super awesome dads,” Sarah Mengon told the television station. “And I’m really lucky. So thank you everybody for following our little story.”
