Kelly Ripa and Mark Conseulos' oldest son is officially all grown up!

Michael, 19, headed off to college on Saturday, but before he left, he posed for a sweet photo with his younger siblings, 15-year-old sister, Lola, and 13-year-old brother, Joaquin.

Kelly didn't get too teary-eyed in her Instagram caption, instead making a cute joke: "Saying goodbye to big bro, the college freshman. (Whilst conspiring to take over his bedroom.) ????."

The Live With Kelly! host is clearly proud of her not-so-little boy. In June, she shared a photo of the high school graduate celebrating his next stage in life ahead of the whole family celebrating his big day at Locanda Verde restaurant in New York City.

"The Graduate, his father, his brother, his grandfather. Congratulations HE! We are so proud. ??," she captioned the Instagram pic of the three generations of Consueloses.

There's been a ton of celebrating this summer, as the very next day, the family celebrated Lola's 15th birthday.

"Because yesterday was big bro's graduation we are officially celebrating Lola's 15th birthday today. Happy birthday Lola! We love you so much! #quince," she captioned a sweet Instagram pic of the birthday girl and her older brother.

It's hard to believe how grown up Kelly and Mark's kids are! It's not surprising, however, that they've got some of their parents' signature sass. In fact, when Michael attended the Nine Lives premiere with his dad and siblings last month, Lola threw a little shade at her famous father.

"I'm like, 'You're actually kind of cool. I didn't think so at first -- now I think you're cool,'" she told ET.
