Superstar Shah Rukh Khan's mornings are becoming sweeter, courtesy his youngest son AbRam.

"I have a new alarm clock & it does not have a shrill scream or a monotonous robotic tone but a smile that awakens my heart. My lil AbRam," SRK posted on his Twitter page.

The doting father raises three children - Aryan and Suhana, whom he had with wife Gauri, and AbRam, who is Gauri and SRK's son via surrogacy.
