Jada Pinkett Smith thanks ‘inspiration’ Will Smith on his birthday

Jada Pinkett Smith says husband Will Smith is the "greatest gift".

The ‘I Am Legend’ actor turned 48 on Sunday (09.25.16) and his wife took to Facebook to share her well wishes with his fans.

In the heartfelt post, she called the star – who she married in 1997 – the "fire of inspiration in my heart".

The post read: "I saw this video yesterday and it reminded me of all the wonderful ways you and I have made a difference together on this planet. We do so much good in this world together, Will and there is so much more to come. You have been the greatest gift to me in that way, by being a fire of inspiration in my heart.

I love you always. To the king of kings…Happy Birthday!!!! Jada (sic)"

Along with the special message, the 45-year-old actress shared a video in which fans are able to relive part of the ‘Independence Day’ actor’s journey to an underdeveloped country. In the video, he shares the good news that he and Jada had managed to raise $789,000 to be used for water projects.

And Jada wasn’t the only family member to wish the ‘Men In Black’ star well on his birthday, as daughter Willow, 15, took to Instagram to share a tribute to her dad. The ‘Whip My Hair’ singer uploaded a throwback picture to the website that saw a young Willow in the arms of her famous dad.

The caption simply read: "<Happy birthday dad> (sic)"

Will also has 18-year-old son Jaden with Jada, and 23-year-old Trey from a previous relationship.
