"They feel peaceful staying there for now," a source told E! News at the time. "Gigi wants the most privacy for their baby and wants to be able to raise her privately."
E! News had also previously reported that Gigi has been delighted to adjust her life to include her bundle of joy.
"Gigi is very tired but is already an amazing mom," an insider revealed. "The first couple of weeks have been a hard transition, but she hasn't complained and is very elated to be a mom."
