Forget Donna Martin: Tori Spelling is about to have a few high school graduates on her hands very soon.
The Beverly Hills, 90210 alum proved that her two "oldest babies" are all grown up by sharing a photo of daughter Stella, 15, and son Liam, 16, heading to their high school homecoming.
For the occasion, Stella opted for a blue dress with Converse sneakers, while her older brother donned a black-and-white patterned shirt, dark jeans and platform boots. Tori—clad in a white crop top and black pants—was pictured standing between the towering teens.
"I'm sorry, little Monkey and Buggy can't come to the phone right now," she wrote on Instagram Oct. 1. "Why? … Oh, 'cause they're grown!"
The 50-year-old went on to quip that Stella and Liam will always "appear their 2 and 3 year old selves with me holding their hands," though they're now "both taller than me."
"These 2 I can proudly say lead with kindness, empathy, and confidence," she continued. "But, they are wise and aware and just really cool humans."
Gushing that she's "proud to be their mom," Tori added, "I trust these 2 because they are just good kids and GET IT! So filled with love and beaming with proudness as mama helps baby birds take flight. No doubt these 2 will soar! And, best of all, they deserve to!"
In addition to Stella and Liam, Tori shares kids Hattie, who turns 12 next week, Finn, 11, and Beau, 6, with estranged husband Dean McDermott.
Earlier this summer, Dean shared in a since-deleted Instagram post that he and Tori had broken up after 17 years of marriage. "It's with great sadness and a very very heavy heart that after 18 years together and 5 amazing children, that @torispelling and I have decided to go our separate ways, and start a new journey of our own," the Chopped Canada host wrote in a June 17 post. "We will continue to work together as loving parents and guide and love our children through this difficult time."
The 56-year-old continued at the time, "We ask that you all respect our privacy as we take this time to surround our family with love and work our way through this. Thank you all for your support and kindness."
Since then, Tori experienced a medical scare that resulted in a multi-day hospitalization. However, she also found joy ringing in son Finn's 11th birthday last month.
"Finn Davey I couldn't be more proud of the sweet, kind, hilarious, brave, witty, and smart beautiful human you are!" she wrote in a birthday tribute Aug. 30. "The day you were born I not only realized how strong we both are but that you wanted to be here so badly that you are destined to do amazing things! I know this because I know your heart and soul."
She added, "I can't wait to watch what you'll accomplish for yourself and others."
