Remember Kelly Ripa's son? The boy is all grown up and stuns with his looks

Although most people remember him as a baby, he's not a baby anymore, and many people are noticing.

It's really hard to think about it, but Kelly Ripa and her husband Mark Consuelos' son, Joaquin, is already in high school.

According to Closer Weekly, Kelly Ripa took to Instagram to share a picture of the 15-year-old boy with his backpack in tow and all ready to start his first day of high school.

The American actress posted it to Instagram on Tuesday, September 5, 2017, as she wanted to share a photo of him on his first day.

The same outlet explained that Ripa's fans went crazy over how grown up and handsome the boy is, flooding the post with thousands of comments.

In less than a week or two, the picture gained over 103,000 likes and over 1,600 comments supporting the actress. The Live With Kelly and Ryan star captioned her son's photo:

'How is the newborn baby a freshman in high school???? HOW???'

Ripa, who tied the knot with Mark Consuelo in 1996, is also a parent to Joaquin's older siblings, 20-year-old Michael and 16-year-old Lola.

During an interview, the actress said she works hard to be a good mother. "Nowadays, parents are so careful and they're so good at parenting and I became that mom," she explained.

A few months ago, Ripa told a funny story about when her son brought a crazy inappropriate item to school by accident. The book, I Am A Pole (And So Can You!), is about a stripper pole authored by Stephen Colbert.

Joaquin brought the book back home and said his teacher wouldn't finish reading it out loud. "I'm not sure if you had read this first," the teacher told Ripa, claiming that it wasn't appropriate for nine-year-olds.

During The Late Show, she admitted that she will never forget the moment, claiming that it was still the greatest school memory she has with Joaquin.
