Sridevi's nephew Avishek Karthik: Family ties of Sridevi

Karthik is the brother of actress Maheswari (I think? - can someone who knows correctly inform/enlighten us?!) and the nephew of actress Sridevi. 

There are several Instagram accounts named after him so we are not sure which is real and which isn't (he hasn't got the 'blue tick' of approval from insta). There are several pics of him over the years with Sridevi. 

Avishek Karthik remains close to Sridevi's kids till date. 

Update: Sridevi’s nephew, actress Maheshwari’s brother Avishek Karthik seems to have an identity crisis. Launched under the name Deva (in his poorly received first film) back in 2011, in 2020, he was renamed Udhay Karthi for the gangster movie Dinosaurs. A consistent track record of flops, perhaps its not the screen name that’s the issue! A rose by any other name...
