‘Little Couple’ Cast Have a Water Fight in New Sneak Peek (Exclusive Video)

The Klein family summer tradition kicks off in newest episode of reality series

A Klein family tradition is showcased in the new episode of TLC’s “Little Couple.”

In this exclusive clip (above) from the latest episode, battle gear — dolphin squirt gun or whale squirt gun? — are chosen and a water fight gets underway.

Since its premiere in 2009, “The Little Couple” has followed Bill and Jen Klein as they move through life with achondroplasia, a form of short-limbed dwarfism.

Over the course of the show’s seven seasons, the Kleins have documented their marriage, the adoption of their two children and Jen’s cancer diagnosis.

“The Little Couple” airs Tuesday nights at 9 p.m. ET on TLC.
