Justin, Hailey Bieber decide to 'stay low-key' as celebrity parents

Hailey and Justin Bieber are still figuring out their lives as new parents.

After the couple welcomed their first son, Jack Blues Bieber in August, this year, the 30-year-old Baby singer and the 28-year-old beauty mogul have still remained quite private over their parental aspect of life.

A source revealed to PEOPLE magazine that "they’ve been trying to stay as low-key as they can since Jack arrived.”

"They’re very excited but becoming parents and having a newborn has been a big adjustment for them," the insider further mentioned, adding "They’ve had a lot of support.”

Even though the couple has not been seen out in public much after becoming parents, America’s sweetheart couple did share a glimpse of their baby boy on Halloween.

In a series of pictures uploaded on Justin’s account, the family of three put on iconic costumes from the popular animated series, Kim Possible.

The Sorry hitmaker and the Rhodes founder dressed up as Ron and Kim Possible, while Jack Blues was dressed up as Ron's pet naked mole rat, Rufus.
