It’s hard to believe The Little Couple has been a part of our lives for almost a decade! The TLC reality show, which follows Jen Arnold and Bill Klein, started filming back in 2008. A lot has changed for the married duo since then!

When the series kicked off, the pair — who have similar rare types of dwarfism — were living in Houston and hoping to start a family. They’ve since had their ups and downs: kids Will and Zoey, a major move, Jen’s cancer diagnosis, a lawsuit, and more.

Now that the show has returned for its ninth season, it’s time we refresh ourselves on Bill’s better half. Read on for everything you need to know about the reality TV mama in 2017.

Where did she grow up?

Jen was born on March 10, 1974, to parents David and Judy Arnold. The now-43-year-old grew up in Orlando, FL, alongside brother David Arnold. She then earned her undergraduate degree at the University of Miami in Florida before attending Johns Hopkins School of Medicine in Baltimore. She later completed her pediatric residency and masters of medical education at University of Pittsburgh Medical Center.

How tall is Jen?

The mother of two has Spondyloepiphyseal Dysplasia Type Strudwick, similar to the type of dwarfism her husband has. She is 3-foot-2, and has had more than 30 surgeries for her condition.

How did she meet husband Bill?

The future married couple met when they were just 10 years old and both getting treated at a Baltimore hospital. At the time, she was in for surgery, and he was undergoing physical therapy.

Where does she live?

The family lived in Houston for many years before recently relocating to Florida — just weeks before the city was hit by Hurricane Harvey. They now live in St. Petersburg, close to Jen’s family and her new job.

Where does she work?

After a lengthy tenure at the Texas Children's Hospital, the neonatologist secured a new position with Johns Hopkins All Children’s in Florida. She gushed, “The opportunity at Johns Hopkins All Children’s is a perfect fit personally for me, my husband, and two kids, and professionally with the growing education and research resources at the hospital.”

How is her health?

In December 2013, Jen revealed she’d been diagnosed with stage 4 choriocarcinoma, an uncommon form of cancer caused by a non-viable pregnancy in 2013. A year later, after months of intense chemotherapy, she announced she was in remission. “I had my official last chemo treatment, and while I’m hesitant to say I’m cancer-free — maybe that’s common for people who have had cancer — I’m doing great,” she said at the time.
