Kendra Wilkinson's son Hank IV isn't so little anymore.

The Girls Next Door alum shared a rare glimpse into life with her 14-year-old, celebrating his acceptance into Oaks Christian School with a sweet tribute. 

Alongside the photo of Hank IV donning a shirt with the private school's logo and holding his acceptance letter, Kendra wrote on Instagram April 24, "I love you so much and watched you work hard to get to where you are. I'm so proud of you my boy. Keep going!!!"
