Harshaali Malhotra referred to Katrina Kaif as 'aunty' while wishing the latter a happy birthday on social media.

The Bajrangi Bhaijaan kid, however, found herself being trolled. The aunty tag did not go down well with the star's fans.

They felt she should have referred to Katrina as didi. The actress, however, came to Harshaali's rescue and thanked her from the bottom of her heart.
