Justin Timberlake and Jessica Biel welcomed son Silas Randall Timberlake earlier this month, but aside from a possible Instagram post and/or a magazine spread, don't expect to see the celebritot anytime soon!

While Jess and JT will stay in Los Angeles part of the time with their newborn son, they plan on raising him at their home in Big Sky, Montana. "Their house is all set up for the baby," the insider tells Us Weekly. "They want to raise him out of the spotlight." Another source added that "Jessica is happiest when she's in the mountains."

"Jess is opening her kids' restaurant, Au Fudge, near L.A. in five months and has tons of meetings," a pal tells the mag, adding that the actress will be spending a significant amount of time in SoCal as well. Good thing they have a mansion down here too!

"Jessica sees herself as a mom of boys, so it worked out perfectly," the source continued. "Justin is so excited, he doesn't know what to do with himself!" Awww!
