"Happy Birthday, my Bean. 15 years old today!!" he wrote. "When you were born it took about 2 seconds to realize that I was willing to die for you. Thank you for correcting my heart – and teaching me how to love without constriction or condition.”
Along with the heartfelt message, the former Fresh Prince of Bel Air star also shared an adorable picture of himself carrying a young Willow. In the snap, Will lovingly gazes at the tot, who is wearing a cute pink dress with sequin detail as she holds onto her dad.
The daughter of Will and Jada Pinkett Smith first caught the public’s attention in 2010, after releasing her first single, Whip My Hair, which eventually went platinum.
The pretty teen made her acting debut in her dad’s movie, I Am Legend, in 2007. She also recently landed herself a modelling contract with the agency that represents models including Kendall Jenner.
Tender Will doesn’t just show his sweet side for his children – the star also showed just much he loves his wife Jada with a tender Facebook post celebrating her 44th birthday in September.
He posted a throwback picture of the couple at her mother’s house 20 years ago, telling her: “Of the nearly 3.96 Billion women on the planet – there is only 1 that I want to spend the rest of my life with.”
Will also totted up the number of candles he has watched his wife blow out and the times he had told Jada he loves her.
The power couple married in 1997 and have two children – 17-year-old Jaden and 15-year-old Willow.
