Finally, some good news for Jen Arnold and husband Bill Klein! The stars of TLC’s The Little Couple have had a tough few months following Jen’s cancer diagnosis, but things are only getting better for the pair. Following Jen’s announcement that she’s officially in remission earlier this month, she and Bill are now introducing us to their newest addition, adoptive daughter Zoey, 2!

"She is a very strong personality," Jen tells People about the adorable toddler. "She is a happy girl."

The neonatologist and her pet store owner husband traveled to India to pick Zoey up, where Jen unfortunately experienced severe bleeding and complications from her illness. She had undergone weeks of chemotherapy treatment for a rare form of cancer, but she is luckily now on the mend!

Now, the couple’s son Will, 3, has a new friend to play with!

"Zoey loves riding on cars and Will loves pushing her around," says Arnold. "It is the cutest thing ever." How sweet!

Tune into the new season of The Little Couple when it premieres on Tuesday, March 4, at 10 p.m. ET on TLC, where we will see when the couple first meets Zoey!
