What does Marilyn Monroe mean by My Heart belongs to Daddy?

[Vivaldi]

She doesn't mean her actually dad by it, right?

Does it mean someone who is old enough to be her dad instead of her actual dad?

It is non sexual. Every girl loves their dad in a platonic way.

[Vivaldi]

Not where I live.

When my father asked me this, I said she must have meant someone that is at the age of her dad... I was mistaken then.

He has a 10 year old daughter by the way (our mothers are different)
