Georgia didn't pose in the photo with her son, but he was seen gazing into the camera while looking super stylish in a black hoodie.
"Boy back for the weekend," the doting mum wrote, before adding: "#sopleasediamnotevengoingtouseacomedyhashtag."
Georgia gave birth to Ty when she was 17, and her husband, David Tennant, adopted him shortly after he and Georgia married in 2011.
The couple also share Olive, ten, Wilfred, eight, Doris, six and Birdie, one.

One follower wrote: "The best! Enjoy your time together," while another added: "Awww, yay! Enjoy your weekend with him - hope you guys have a lovely one."
Another hoped that the teen, who is an actor, would follow in his adoptive father and grandfather's steps and play The Doctor in Doctor Who. His grandfather, Peter Davison, played the fifth incarnation of the titular role, while David played the tenth.
Georgia's husband is a doting father to each of his children, and he'll be no doubt thrilled to see Ty back as well.
Last week, Georgia melted fans' hearts when she shared a picture of David reading The Wolves in the Wall to their youngest child, Birdie.

The Scottish actor looked incredibly stylish in a cashmere jumper and jeans, while the book obscured their youngster's face.
"Never too young for @neilhimself," Georgia joked. "And the baby likes it too. #goodnightomens."
The image sparked a huge fan response, with the book's author, Neil Gaiman, responding: "I just love that he's reading it, and that she's liking it."
