It's high time their families meet!

We caught Justin Bieber and wife Hailey Baldwin picking up his mom Pattie Mallette from her $120-a-night Holiday Inn hotel this afternoon in LA, just one day after the couple grabbed lunch with the model's father Stephen, and we have a feeling the parents are getting involved in the wedding planning!

Of course, we all know that JB and HB secretly tied the knot in a courthouse ceremony in September, but they're still planning a blowout ceremony, and they probably want Pattie and Stephen's input on their big day.

A source tells X17:
    "Justin loves Hailey's dad and actually spends a fair amount of time with him. His mom Pattie lives far away, so he wanted her to visit and spend some time really getting to know his new wife and her parents. Pattie was close with his ex Selena Gomez, but she just wants what's best for her son, so she's very friendly with Hailey as well."

The Bieber clan and the Baldwin clan are bound to spend holidays together in the future once a baby Bieber arrives, so it's good they're bonding now!
