Shah Rukh Khan's son Aryan was arrested on October 3 in connection with a drug seizure on a cruise ship off the Mumbai coast.
However, the special Narcotics Drugs and Psychotropic Substances (NDPS) court is hearing a plea for bail to Aryan Khan, Arbaaz Merchant and Munmun Dhamecha in the matter.
It takes a "lot of courage, grit, will-power, and strength" to get back up during the "difficult moments", Shilpa Shetty said in her Instagram post.
Crown Prosecution Service barrister Helen Malcolm argued against permission to appeal by reiterating that the expert evidence on Nirav's mental health has not been disputed.
Mallya had cited the poor condition of the jails in India to avoid extradition and possibility of being lodged at this jail.
