"Justin is so excited, he doesn't know what to do with himself," a source close to the couple said. "Jessica sees herself as a mom of boys, so it worked out perfectly,"the insider told Us Weekly magazine. "Their house is all set up for the baby. They want to raise him out of the spotlight." But they plan to return to their Hollywood Hills mansion in the near future when Biel opens her new restaurant, Au Fudge, here. "Jess is opening her kids' restaurant, Au Fudge, near LA in five months and has tons of meetings," a second source explained. The pair are getting support from friends and family members, including Timberlake's mother, Lynn Harless. The friend said: "Lynn jokes she wants Silas all to herself!" (Source: IANS)
