The singer and her husband Swizz Beatz welcomed son Egypt eight months ago, and she said that he loves a good chuckle. He even laughs at adult jokes.
'He loves to laugh,' she told People magazine. '[He laughs] at everything. I'll say a joke that's totally a grown person's joke and he'll laugh. I'm like, 'Ha! You get me'.
'I do silly noises on his cheek and he'll just crack up. A person making a silly face, me tickling him. He laughs at everything.
'If he wants to laugh, he'll egg you on, so that you'll start to make him laugh... He has one of those big Gerber baby giggles, and it's huge and perfect.'
And the 31-year-old added that he is turning out to be the perfect traveling companion.
'He's a rock star champion flyer. I can take him on a six or seven hour plane or if we take the train from Paris to London, he rolls with it. His temperament is super cool,' she said.
