Yesterday, Greg Jennings, the father of “I Am Jazz” star Jazz Jennings, completed another year of life.

And in celebration to date, his children and wife paid him a lot of tribute on Instagram.

“Happy birthday to the best dad in the world,” Jazz wrote.

“Happy birthday, my love, my rock, my soul mate who’s always been ‘my one’” his wife, Jeanette Jennings, wrote. “I love you so much!”
