Now, we all know what new mums are like.
They like to brag about their babies as if they're the most gifted children ever born.
But Nicole Kidman's taken the proud mum act way beyond the limit.
While most three-month-olds spend their days dribbling, Nicole reckons her daughter, Sunday Rose, has been swotting up on general knowledge.
She told Us magazine: "She is reading the encyclopedia."
Well, in the crazy world of celebrities, we know that anything's possible.
Breathe a sigh of relief though, as we can reveal that Nic was only joking. Phew.
However, the actress did reveal that Sunday is already smiling, which is advanced enough for us.
Nobody likes being outsmarted, especially by a baby.
