Catherine Zeta-Jones wants to go to university.

The 48-year-old actress - who left school when she was 15 - shared the excitement of her and husband Michael Douglas' 18-year-old son Dylan when she helped him to move into his dorm at Rhode Island's prestigious Brown University over the weekend.

She shared a black and white video of her son's new home on Instagram and wrote: ''Jumping for joy this morning. The start of Dylan's college life.

''He is bursting with joy, as am I ! Wish I could enroll too!! Fantastic! Enjoy every second #thejoyoflearning.(sic)''

The 'Chicago' actress - who also has 15-year-old Carys with her spouse - went on to wish her son luck in the new chapter of his life.

She added: ''Let the lectures really begin! I love you Dylan. Good luck in the next exciting and enlightening chapter of your life.''

Michael, 73, was also spotted in the video as Dylan said goodbye to his family and was on hand to help his son move in to his new room and continue his academic studies.

Dylan shared a picture to his own Instagram account of his dorm room and captioned the post: ''A new home''.

The teen's room features iconic Union Jack cushions on his bed, in honour of his British roots via his Welsh mother, and a Rolling Stones poster on the wall.

Meanwhile, 'Ant-Man' star Michael recently admitted he and his father, 101-year-old actor Kirk Douglas, have warned his kids - including Cameron, his 39-year-old son from his marriage to Diandra Douglas - they may not be able to replicate their movie success in their own lives.

He said: ''We've talked all about it. They've seen good fortune but they understand it's really about... if they have that joy of performing and want to do it, then great. It's not easy.

''Second generations are rare in terms of success. Or third generations. So we wish them well. You're always happy to see someone young have something they're interested in.''
