Will Smith's son Jaden Smith has announced he is opening his own restaurant.

The 19-year-old star is an actor and rapper and also runs his own clothing and lifestyle brand MSFTSrep but it seems he's not satisfied with all his different jobs.

Jaden - whose parents are Hollywood actors Will Smith and Jada Pinkett Smith - is now going to enter the dining out market by running an eatery.

He announced his new venture on Twitter with a tweet that simply read:

When not focusing on his restaurant, Jaden - whose 16-year-old sister Willow Smith is a pop star - has also been pranking people by telling strangers he is "legally crazy".

He tweeted:

Jaden's restaurant plan should come as no surprise as he previously revealed he has some "dope" things coming up at the end of this year.

The 'Karate Kid' star said: "At the end of 2017, I'm gonna do some dope - some really, really dope, inspirational stuff that's beyond just music and clothes. Nothing about this life makes any sense."

Jaden's father Will has always been fulsome in his praise for his socially conscious son, and has often talked about how much he respects his drive for success in so many different fields.

The 'Suicide Squad' actor said: "He's really coming into a space where he understands who he wants to be, and the big thing that I feel good about with my kids [and] the thing that my grandmother was able to instill in me was the responsibility to your family, your community and to the world. Everything you do is not just for you. You are connected to everything and everybody and you have a responsibility in everything you say and do out in the world to care not only for yourself, but for everybody."
