During a Q&A session on Twitter with fans, the 'Chennai Express' star was asked, if he wishes to have a brother in real life.
The 50-year-old actor replied, "My two boys are now like my friends and brothers and everything so I am ok. And there is always bhaijaan."
After years of cold war between them, Shah Rukh and Salman, 49, are back as friends and have often been seen heaping praise on each other.
Shah Rukh, who is gearing for the release of his romantic-comedy "Dilwale", was also asked about when he would finish working on autobiography.
"How is writing of your book going on? How does it feel to write the heart out?" asked his fan, to which the actor replied, "A very very long process and slow... giving your heart out takes a bit of time."
