A third added: "Happy birthday bright soul!! You continue to shine bright Gigi." And a fourth paid tribute to Vanessa on what would be a difficult day for her.

"I think you're truly amazing, someone should never have to have lost as much as you did all at once," they said. "I hope today isn't too painful. All my love."

Vanessa has three other children, and in March she had a reason to celebrate as her daughter, Natalia was accepted into the University of Southern California.

The proud mum shared a video of her daughter jumping with joy and shouting: "I got it, I got in!"

"You pushed through the most excruciating pain imaginable and you succeeded. I wish Daddy and Gigi were physically here to celebrate but I know they're here in spirit. We love you so much! #USC #Trojan #FightOn."

The mother-of-four later showed off a video of the guest room fully decorated with celebratory balloons and packed with merchandise from the university, including a personalised pair of trainers that took Vanessa three months to make and featured Kobe's name on the side.

"Congratulations Nani Banani!!!!!! If you wouldn't have been accepted I would've had to have stabbed these balloons in the guest room and have thrown all this away. Thank goodness you got in.

"I had these shoes custom made for @nataliabryant Daddy and Gigi are ALWAYS here. Forever and always Principessa. #USC #TROJAN #FIGHTON," she captioned the sweet clip.
