It's been over a year since Paris Hilton shocked her mother, Kathy Hilton, after keeping her son Phoenix's birth a surprise. Paris and her husband Carter Reum welcomed their son secretly via surrogate. It was so secret that Paris didn't even tell her mother in order to minimize the risk of the media and public finding out. The moment that Kathy laid eyes on her then-week-old grandchild, she was brought to tears. The sweet moment is captured in Paris' Peacock reality show, "Paris in Love." While appearing on "The Jennifer Hudson Show," Kathy became emotional revisiting the special moment.

"Just watching that again, oh! So beautiful," Kathy said before assuring Paris her tears were happy. "It's a happy time. I couldn't believe it though." Kathy recalled how she felt in the moment, saying she thought Paris was holding a puppy because she and her husband Rick Hilton were grieving the loss of their dog. "Well, Paris is always surprising, I think all of us, she's always doing something. So, when she came out she had these other gifts for me because it has just been Valentine's Day or Christmas, she came out and...I thought it's either a new puppy or a monkey," Kathy explained. "I could not believe it and just so sweet," Kathy said as she dabbed her eyes before excitedly telling the crowd how much Phoenix has grown since then. "He is so long and big and he's getting hair and smiles...it's really something to have my first baby having her first baby and now with London - we have Irish twins."

Paris surprised her family at Thanksgiving with their second baby, London, who was welcomed via surrogate. "I was really nervous. Just to surprise someone with something like that, is quite the surprise, as my mom said I am full of surprises but that was on another level, it was just so emotional too, such a special moment," Paris said.
