And so is his superstar dad Rishi. And before your brains start working overtime, let us tell you that they're head over heels in love with Riddhima Kapoor's six-month-old daughter Samara.
Says the glowing mum, "Ranbir just can't take his eyes off Samara. When I visited them last month, Ranbir just refused to stay away from her.
He'd say, 'Give her to me and you go back to Delhi.' Even in the middle of the night, I'd find him standing next to my bed peering down at Samara!" And the senior Kapoor too is equally besotted.
Neetu Singh reveals, "Rishi wasn't around when our kids were small because of his work. So it's a new experience for him." Well, don't we envy the little darling!
