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

There's no doubting who Catherine Zeta-Jones and Michael Douglas' son takes after in the looks department!

Catherine Zeta-Jones recently shared some rare photos of herself glamorously posing with her 18-year-old boy, Dylan — and we can't get over how much they look alike.

In an interview with TODAY, the 49-year-old actress 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."

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

Along with Dylan, they also share daughter Carys, 16.  

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

Michael has one son, Cameron, from a previous marriage.
