"You and babies will always melt my heart," penned one Instagram user.

A second wrote: "This is the sweetest thing in the world."

Hailey has previously opened up about how she's 'scared' to have children while being in the public eye.

Speaking in an interview with The Times, Hailey was asked if baby Biebers were on the horizon anytime soon, to which she laughed and responded: "I literally cry about this all the time! I want kids so bad but I get scared. It’s enough that people say things about my husband or my friends.

"I can’t imagine having to confront people saying things about a child.”

She continued: "We can only do the best we can to raise them. As long as they feel loved and safe."
