Rainbow Aurora's getting so big!
Holly Madison brought her adorable daughter to see Santa Claus at the Fashion Show Mall on Thursday in Las Vegas.
The former "Girls Next Door" star looked beautiful in her black and white vintage dress and black pumps. It also looks like Madison's gone back to her signature blonde color, after dying her hair a dark red in October.
Little Rainbow looked picture perfect for her meet-and-greet with Santa as well, wearing a festive plaid red dress, white leggings and pale pink shoes.
The Playboy model has been keeping a low-profile since welcoming her baby girl with hubby Pasquale Rotella a little over a year ago.
"I am much more selective about the appearances I do because of the time it takes away from Rainbow. I can't be this Tasmanian devil, whirling around to party after party every night anymore," Madison revealed in an interview earlier this year.
Well, motherhood sure looks good on the "Peep Show" alum -- what do you think about her adorable outing with Rainbow?
