Shruti hassan was recently seen at the Luck press meet in a different shaped nose. It looks quite sharp and not obviously long. The other 2 photos are from Luck trailer and some event last year. You can clearly see she has undergone a nose job.
But she should have gone for it before she shot for the movie Luck , it wouldnt have been so obvious then:)
I like her nose now:)
And yesh she has tattoo on her back which spells shruti hassan in tamil
