HipHopDX.com has an interview with Biggie's daughter:

HHDX: There was a lot that hip-hop pulled from B.I.G. before and after his passing, but not too many people got to see the personal side of Frank White. So, for those who were the die-hard fans – what is something that no one would know about him?

T’yanna: I would have to say that for anyone who thinks that he’s all what he says in his lyrics… that he’s all rough, tough and hard, you’d be surprised. He was a sensitive guy. He was always in a happy mood around us. He loved everyone that he was close to. I know that in documentaries or specials, you’d see that he was a funny man. You could always hear him telling a joke… all the time.
