This will be another baby that's being welcomed into The Hills family. Co-star Audrina Patridge gave birth to her first little one, a girl, in the summer last year.

Port's pregnancy also comes just after her friend and fellow Hills alum, Lauren Conrad, announced she was also expecting a child with husband William Tell in January.
