She may have starred in some of Hollywood’s biggest blockbusters, but Sandra Bullock‘s two kids — 9-year-old Louis and 7-year-old Laila — aren’t fazed by her superstardom. In fact, a source close to the Bird Box star recently told Closer Weekly that her little ones don’t even think twice about their mama’s fame and fortune.

“They don’t really know that their mother is a huge movie star, they just know her as mommy,” the insider shared. “Louis and Laila are two of the most polite and well behaved children I know. There’s not an ounce of brattiness, what you might expect from Hollywood kids, and that’s because Sandra is nothing but a mom to them.”

The 54-year-old is getting by with a little help from her boyfriend, Bryan Randall, who the source said has been a great influence on their whole family. “They’re raising two great kids and its a testament to both Sandra and Bryan’s down to earth parenting skills,” the insider added.

Even though Sandra is technically Louis and Laila’s only parent — The Blind Side actress adopted her son in 2010 and then adopted her daughter in 2015 — Bryan has made an amazing dad. “Sandra and Bryan consider themselves a solid, committed, family unit,” the same source previously shared with us.

“The kids are growing up so fast and Bryan couldn’t be more involved in their upbringing,” the source also dished to us. “The kids adore Bryan and of course Sandra still pinches herself that she’s been so lucky finding Bryan.”

It’s been pretty obvious that the adorable foursome love spending time together, considering they’ve been spotted left and right as of late. The source explained that while Sandra, Bryan and her two kids “prefer private time, like hiking” and “exploring nature,” they equally enjoy “outings to public places and restaurants, like their recent visit to Soho House in West Hollywood.”

Sandra and Bryan, who have been together since 2015, may be pretty hush-hush on their relationship, but the source insisted that the two couldn’t be happier. “They don’t talk about their relationship status that much, but it’s pretty clear what they have is a very special bond,” the insider explained. “Bryan proudly wears a wedding band on his wedding finger and there’s no doubt that he’s Louis and Laila’s dad.”
