Former Australian "Dancing With the Stars" professional Kym Johnson-Herjavec and her husband Robert Herjavec are holding onto the last bit of summer.

The "Shark Tank" star, 57, couldn't help but share a fun throwback snap from one of the couple's past beach days.

In the Instagram picture, which showed off the duo's sculpted physiques, the pair was seen playfully jumping into the air while holding hands.
