He said: "I have no idea where that came from. I will ask her, it is very interesting. With the excitement of the baby, you don't go into the name just yet.
In the interview however, he assures us that he’s pretty sure there is some sort of story behind it because it is after all an unusual name.
"When I heard it, I thought it was my job just to go 'absolutely.' I will ask about Sparrow and she will have a story."
Lionel also discussed how proud he is of his daughter Nicole completely changing her life around.
Lionel told FOX News: "One thing I love about Nicole is when she makes her mind up to do something, it's done. When Joel came along she found that one person, that partner that she needed to get her into that mode of taking care of herself and paying attention to her lifestyle.
"And then of course when Mouse number one and Mouse number two came along that was it, and I can tell you right now she is a different person."
Nicole has definitely changed her life around. She is definitely one of those celebs was on the wrong path and quickly made a u-turn to get back on the right track.
