Social media star Chahat Fateh Ali Khan has been served with a legal notice demanding Rs180 million in damages for defaming legendary musician Ustad Nusrat Fateh Ali Khan. The notice was issued by Mian Muhammad Umair Niaz on behalf of Qaiser Munir Khan and sent to Chahat's residence in the UK.

The notice states that if Chahat fails to respond within 15 days, a defamation lawsuit will be filed in court, Express News reported.

Chahat is accused of tarnishing the name of Nusrat Fateh Ali Khan, offending the people of Faisalabad, and violating the Copyright Act. The notice claims Chahat falsely portrayed himself as a relative of the late musician and damaged Nusrat's legacy through his singing.
