It's Sohail Khan and Seema Khan's son Nirvan Khan's birthday on today on December 15. The star kid, who turned 20 this year, celebrated his special day with his family at his residence in Mumbai. Present at the birthday celebration were Sohail Khan, Seema Khan, their younger one Yohan Khan, actor-director Atul Agnihotri, his daughter Alizeh Agnihotri and son Ayaan Agnihotri, Arbaaz Khan with son Arhaan Khan, Arpita Khan and Aayush Sharma's little ones - Ahil and Ayat, and few other family members.

We got out hands on some pictures from the birthday celebration, all thanks to Seema Khan and Atul Agnihotri's social media posts. Seema Khan shared pictures and wrote in the caption, "Happy birthday my love @nirvankhan15 #mybestfriend #mygreatestblessing #myworld."
