Briana Culberson's Son Troy Is Trying Out a Seriously Mature Look

It feels like only yesterday when Vicki Gunvalson became a grandmother after her daughter, Briana Culberson, welcomed her first child, son Troy, into the world (clip above). But that was actually in 2012, and that bouncing baby boy is now 6 years old and growing into a little man right before our very eyes. 

That has never been more the case than in a photo Troy's dad, Ryan Culberson, recently shared on Instagram. Vicki's son-in-law posted a photo of Troy getting ready for Christmas by getting a fresh haircut. And the 6-year-old went for a new grown-up look. As you can see, Troy tried out a fade for the first time, and it's more mature than we've ever seen The Real Housewives of Orange County kid look before, as his dad pointed out on Instagram. "Mr. Serious decided he wanted a part," Ryan wrote in the caption to the pic, where he also noted that Troy looks like he's "#6goingon16."

Ryan couldn't believe where all the time has gone when he celebrated Troy's birthday on Instagram this fall.

Troy's 4-year-old brother Owen is also becoming "a little man," as Ryan pointed out on Instagram earlier this year.

But don't worry; Troy and Owen are still Briana and Ryan's little boys. The two looked absolutely adorable playing outside with mom and dad during a snow day earlier this month.

Now if only we could figure out how to slow down time just a little bit...
