Catherine Zeta-Jones' son is all grown up and looks JUST like his mum

Catherine Zeta-Jones, 48, and Michael Douglas, 73, are the proud parents of two teenagers. 

The couple sent their son 17-year-old Dylan - who looks a great deal like his famous mother - off to his senior prom.

"Prom Proud!" Catherine said on Instagram. "Graduation around the corner! So proud of you Dylan. College-bound! Love you so."

Dylan donned a black tux and a bow tie for the fancy occasion marking the close to his high school years. 

He wore a white rose boutonniere that matched that corsage on his date's wrist. 

He was accompanied by a girl in a stunning black lace dress, who wore her hair in soft curls.

Catherine and Michael have been happily married for nearly 18 years. 

Along with Dylan, they also share daughter Carys, 15.  

When asked by ET what has made their marriage so successful, Douglas said "mutual respect." 

In an interview with TODAY, Zeta-Jones talked about how fast her children are growing up. 

"These years have been so important in that you never get them back," she said.

"I've got two great teenagers and I love them. I've had all this wonderful time and I'm so excited to see which way they're going to go."

Michael has one son, Cameron, from a previous marriage, and recently became a grandfather with the birth of Cameron's daughter Lua.
