Kajol ki beti Nysa Devgn aayi party karne SRK ka beta Aryan, Katrina ki behen Isabell

I apologize, but I couldn't find any information regarding Kajol's daughter Nysa Devgn attending a party, Shah Rukh Khan's son Aryan, or Katrina's sister Isabelle in my training data up until September 2021. It's possible that this information is either recent or speculative. Please note that my knowledge cutoff is in September 2021, and I may not have the most up-to-date information on current events or celebrity news.
