Heather Dubrow's son, Nick, will soon be heading off to college — but which one? That was the question at hand as the decision for his top choice school, Loyola Marymount University, recently came in.

Heather, who returns to The Real Housewives of Orange County in the upcoming Season 16 after a five-year hiatus, shared a video of Nick on her Instagram on November 23 receiving the decision from Loyola Marymount. "OPENING THE DECISION EMAIL FOR [Nick's] FIRST CHOICE COLLEGE," Heather captioned the video. "THIS IS SO NERVE WRACKING!!!!!!!"

The clip shows Heather, Nick, and his twin sister, Max, anxiously awaiting to see whether he has been accepted to Loyola Marymount. "Dude, I can't open this," Nick says nervously as he checks to see the college's decision online.

But it turns out that Nick had nothing to be worried about! We soon see him, Max, and Heather erupt into cheers, smiling as they all hug, signifying that he has been admitted to the school. Heather and Max also jump up and down as they hug, even falling over onto the bed behind them at one point in an absolutely adorable moment.

The comments to Heather's Instagram post are filled with congrats for Nick, including from Tamra Judge ("Amazing. I got chills watching."), Shannon Storms Beador ("Congratulations!!! So happy for you!!!), Gretchen Rossi ("Soo cute! Congrats."), and Emily Simpson, who also left several happy face and heart emojis.

Gina Kirschenheiter especially gushed about the news in the comments. "Awwww!!!!!! Love this! Congrats [Nick]!" she wrote. "I feel like a part of your college journey!! So happy for [you] and your mamma!!!"

Nick's college acceptance has kicked off a major week for the Dubrow family. He and Max also celebrate their 18th birthday on November 24.

Of course, Heather has already marked the momentous occasion in her Instagram Stories, sharing several throwback photos of her twins as infants and promising to post even more as their birthday festivities get underway. "Twins are magical," Heather captioned one photo in her Instagram Stories, adding in another slide, "Love these two so much."

If you follow Heather on Instagram, you know that she is always showing her love for all of her children, which also includes daughters Kat, 15, and Coco, 10. In honor of National Daughters Day in September, Heather said of her girls, "Love you all so much. This is a very old picture but their little faces make me happy."

And to celebrate Nick on National Son Day in September, Heather wrote on Instagram, "You are the best kid and I’m so proud of you! I can’t wait to watch your next chapter!"

When RHOC Season 16 premieres with a supersized episode on Wednesday, December 1 at 9/8c, we'll see just how grown up all of Heather's kids are these days. She gave us a sneak peek at how much they've grown over the years by sharing pics of the family, including her husband, Dr. Terry Dubrow, from RHOC opening titles shoots, starting with Heather's first season on the show, Season 7, all the way to her return in Season 16.

"How it started … how it’s going (swipe to see!)" Heather captioned the collection of photos on Instagram on October 22. "10 years ago I started an adventure on #RHOC! I can’t believe how much the kids have changed and grown and I can’t wait for you all to get to know them! Coming soon!"
