Even dad Saif shared a birthday wish for his dear son. However, he just reposted the same photo that Sara shared on her social media account.

Both Sara and Ibrahim share a great sibling bond. The actress, who debuted in Bollywood with Kedarnath last year, has also been talking highly of Ibrahim in her interviews. She makes sure to express that she and her brother always have each other’s back. In fact, in one of the interviews, while promoting her first film, Sara mentioned how it’s important for her to do good films and be humble with all because she wants to set good benchmarks for her younger brother.

Sara had also revealed how their parents have always been strict with them and have brought them without glamour and glitz. She added that neither Saif nor Amrita allowed her and Ibrahim to attend Bollywood parties or make appearances at events before they turned 18.

On the work front, rumours are rife that Sara has bagged Imtiaz Ali’s next film with Kartik Aaryan and has even started working on it. However, there’s no confirmation on the same and when Kartik was asked to comment on the same, he dodged the question by saying Imtiaz would be a better person to answer it.
