The youngest of Chrisley's siblings, Grayson Chrisley, has grown in front of the Chrisley Knows Best audience. He was born to the famous television star parents — father Todd Chrisley and Julie Chrisley — on May 16, 2006.

Over the years, the Chrisley family has supplied family drama to the audience, unhesitatingly sporting sibling rivalry and estranged relationships among family members. 

But despite all family issues, Grayson apparently has a solid bond with his older sister, Savannah Chrisley, the youngest daughter in Chrisley's household.

Both of them seem to be closer compared to their other siblings, Chase, Lindsie, and Kyle — and it's pretty apparent from his Instagram. More so from Savannah's account, which has chronicled her brother's evolution over the years.

Here are the five pictures from the reality star's Instagram handle that showcase their adorable bond and Grayson's progression until today. 

Grayson As a Teenager!

When Grayson first stepped into his teenage years, Savannah took to Instagram to celebrate the big day for her brother, whom she affectionately calls GrayBug. 

She posted a picture with him on May 16, 2019, flaunting her classy look with black sunglasses and a white T-shirt. Grayson posed close to her, sporting his titan jersey. Together, the brother-sister duo exhibited their million-dollar smiles. 

Besides the picture, Savannah's heart-warming message for her brother stressed the post's value. Heralding Grayson as her best friend, the television personality shared how he had so much love, heart, and maturity for his age. 

Then, sharing her piece of mind, the fashion designer urged her brother to believe in himself. 

You’re gonna be something special gray...don’t ever let anyone tell you that you can’t do something!

At the end of the message, she expressed how lucky and honored she was to get Grayson as her brother. 

Twinning With Sister 

On April 10, 2020, Savannah gave glimpses of her robust bond with Grayson to her Instagram followers. She posted a TikTok video, where the duo lip-synced in a song about twins. 

In the caption, the 23-year-old cited how they were basically twins with similar dress sense and haircuts. Undoubtedly, the post left their fans wanting a similar sibling bond. 

Grayson Turning 15

Grayson has been growing so fast right in front of everyone's eyes. When he turned 15 on May 16, 2021, Savannah uploaded another post for the birthday celebration. 

This time, she posted a gallery of pictures featuring Grayson's old photos. He could be seen embracing Savannah as they laughed together in the very first picture.

Needless to say, the Atlanta native poured her heart for her brother in the caption. She thanked Grayson for being the kindest, loving brother in the world and stated she was proud of the man he was becoming. 

Driving with Sister

The unbelievable evolution of Grayson was apparent to the Chrisley fanbase when Savannah posted a picture of him driving a car on May 26, 2021.

Aside from the fact that he was already driving a car, his maturity was undeniable as he looked straight in the camera. He rocked a black cap and a full-sleeved blue T-shirt with a silver chain. 

Savannah, on the other hand, looked beautiful with her plump lips and blonde bob hairstyle. 

In the picture's caption, the Growing Up Chrisley star joked about how he would be a better driver than her and reiterated how he will always be her little GrayBug. 

Grayson Chrisley Being Unrecognizable 

On August 6, 2021, Savannah's Instagram account let followers see the latest change in Grayson's evolution, and he was unrecognizable because of his height. 

Grayson stood tall as he held his niece, Chloe, close to him. In the caption, Savannah prayed to God to help her let the children become what they were meant to be. She wished that they never feel discouraged to pursue their dreams. 

Fellow Instagram users expressed their shock at Grayson's growth. One user wrote, "He’s so tall now!!!! Where did the time go?!?" Another remarked how the kids were growing so fast. 

Without a doubt, Grayson is growing up fast with every blink of an eye and making his family proud with his kind heart.
