On the last few episodes of The Little Couple, we’ve gotten to know star Bill Klein’s family. From meeting his brothers and seeing them help with Hurricane relief to meeting his dad and stepmom on their trip to the UK, the Klein family has really been present on the most recent season. But on the most recent episode, Bill’s wife Dr. Jen Arnold got to spend some time with her family.

Who are Jen Arnold’s parents?

Jen was raised by David and Judy Arnold in Orlando, FL, and from the looks of social media, the Arnold family is very close. Judy’s Twitter bio reads, “Mom to Jen (of TLC’s The Little Couple) & Manager @ Rocky and Maggies!” Rocky and Maggies, of course, is one of Bill’s many business ventures, a pet store named after the couple’s dogs.

On this weeks episode, the family got together to celebrate Jen’s brother David’s birthday. Jen took to her Twitter while the episode was airing to give fans an inside look at the festivities. “Happy Happy Birthday David!” she captioned the group shot. “Definitely a cake made with lots of love!” It was of course grandma Judy, or NaiNai, who helped kiddos Will and Zoey bake the birthday cake.

Jen’s parents were there for her during the tougher times too. Back when she was diagnosed with cancer in 2014, her struggles were highly publicized. And she made sure to shout out her parents when they were by her side during the intense treatment.

“My parents have been a great support during this challenging time!” she wrote in the caption of a picture of herself lying in a hospital bed with her mother. “Love them!” It’s clear both the Arnold family and the Klein family keep it a priority to stay tight-knit. And we gotta say, that’s why we love them on TV!
