Being a superstar family, it must be hard to find time to relax together but Will Smith took Willow and Jaden down to the beach in Hawaii for a day of relaxing for his youngest son's birthday.

The family set up camp on the beach for the day, with back packs of water, chairs and a gazebo to provide some shade. Trey Smith, who recently graduated from high school also joined his dad and half-siblings but chose to keep his shirt on, unlike his dad Will and brother Jaden.

Willow Smith was seen in her wet-suit before she went surfing, and also in a swimsuit and denim shorts.

It's Jaden's birthday today, and he will be hosting a birthday party later today.

Just a few hours ago, the 13-year-old tweeted: "I Wana Thank Everybody For The Happy Birthday Tweets #LoveMyFans"

Wish Jaden A Happy Birthday Here!
