Jen Arnold Shares Will Klein’s Milestone Birthday

Jen Arnold from The Little Couple dotes on her two kids, Zoey and Will Klein, and this week, she shared about his milestone birthday. TLC fans were blown away because he’s gotten so big. 

The Birthday Boy Is So Grown Up

Two years ago, Will celebrated his thirteenth birthday in New York City, and his mom pointed out that his sister, Zoey loved shopping for the big day. They dined out at a restaurant and already, he looked like a young man. 

“Another birthday in the books! I cannot believe you are 15 @willklein63,” she wrote in her Instagram post on February 25, 2025. You will notice that she tagged her son because he’s had his own account for a while now. Will Klein also started TikTok account a few years ago. 

A Big Cake On His Birthday

The Little Couple fans saw that Jen Arnold also told her boy, “We are so so proud of the kind, fun-loving, giving, and smart young man you have become!” Well, he probably learned about giving because his mom gives so much of her time to her patients, students, and her family. 

Most likely, before you know it, Will starts learning to drive. However, it remains to be seen if he gets a flashy truck like Saylor Waldrop when he does. It’s not known what Jen Arnold and her husband Bill gifted Will this year, but he did get a big cake full of candles. 

Fans React With Amazement

It’s been a long time since TLC fans last saw Will on TV. So, his growth spurt shocked some of them. In fact, the last episode of The Little Couple aired on September 24, 2019. Will Klein was only about nine when the last season was filmed. 

Fans reacted to the photo and they all thought that he seemed so grown up. Here are some replies:

• Happy birthday Will can’t believe you are 15 . I can still remember when your parents went to get you I felt so happy for you and knowing how much you were and have been loved. May God bless you always
• All my best wishes for your birthday Will!!! You are becoming a man! Congratulations and a hello to your lovely parents and sister.
• I remember watching the episode when you adopted him and took him back to America, and same with your daughter, oh how time flies. Happy birthday.

Time does fly, and it’s scary sometimes to see how fast everything seems to happen. One day, no doubt, Will be going to college, and fans of the reality TV show will say the same thing.
