Will Smith’s birthday note to his daughter Willow is SO sweet

Willow Smith turned 15 over the weekend, and her famous dad couldn't resist a little Facebook shout-out.

As the daughter of Will and Jada Pinkett Smith, Willow has lived her whole life in the spotlight, but her dad's message yesterday shows that underneath it all she's just a normal teen.

"Happy Birthday, my Bean. 15 years old today!!" the actor wrote on his personal page. 

"When you were born it took about 2 seconds to realise that I was willing to die for you.

Thank you for correcting my heart – and teaching me how to love without constriction or condition." The message was accompanied by a gorgeous throwback snap of Will and little Willow.

Will is clearly a fan of celebrating birthdays via Facebook – back in September he did some "birthday math" for his wife of 15 years:

Having found fame aged just 11 with her song Whip My Hair, Willow became something of a child star, but she has bowed out of the limelight more in recent years.

"She’s really just developing herself… She’s taking her time to develop her skills, so when she feels like people are ready to know the real Willow, then she will make a comeback," her dad said recently.

Back in 2012, Will came under fire for revealing his son had asked for emancipation from his parents for his 15th birthday.

However in a later interview on The Ellen Degeneres Show, Will insisted his comments had been a "joke," adding, "My baby boy, he's never leaving me, ever. No emancipation for the Smith kids."

As for Jaden, he joked that his dad wouldn't allow him to move out until "'I have a movie that's bigger than one of his movies."
