Siddharth took to Instagram to share a snap of the two and captioned it, "Great catching up with this one after ages!!!! @isakaif #vain."
Salman Khan's production 'Dr Cabbie', featuring Isabelle, though complete in 2014, did not get a theatrical release in India despite Salman's plans. It was touted to be a launchpad for Isabelle's film career in Bollywood.
In 2011-12, Isabelle would often accompany Kat to film events and award shows, but later, she went missing from her sister's side. Isabelle and Harshvardhan (Anil Kapoor's son) also featured in a short film, 'Coming Home' (2012).
In 2014, Isabelle was allegedly involved in a sex tape scandal. However, many claimed it was not her, but her lookalike.
Meanwhile, Siddharth Mallya's debut film, 'Brahman Naman', not just premiered, but also competed in the World Cinema dramatic competition at the Sundance Film Festival in the United States last year.
