Lambert, 38, already has some parenting experience since she’s a stepmom to McLoughlin’s son, Landon, who will turn 4 next month.
Although not much is public about the 30-year-old’s child — with whom he shares with ex Kaihla Rettinger — it is evident the broken family still shares a special bond.
“They keep that part of their life private out of respect for Landon’s mother, but they’re both very much part of his life,” the insider dished. “They just celebrated Brendan’s birthday and had a low-key celebration. They’re very much homebodies so when they’re not on the road they love to just spend time at home with their pets.”
