The duo have formalised their relationship with Kunal proposing the 'Tum Mile' star recently. Soha took to Twitter to share the news with her fans.
"It gives me great happiness to share with you all that Kunal proposed to me in Paris with the most perfect ring in the world and I said yes," she tweeted.
Soha and Kunal have been dating each other for quite some time and have always been open about their relationship.
Soha's mother Sharmila Tagore and actor-brother Saif Ali Khan have always been supportive of their relationship, while the 'Kalyug' star's father Ravi Khemu reportedly said in an interview recently that he would bless the couple whenever they wish to get married.
The young stars have worked together in 2009 film '99'.
