On September 4, Celina remembered her late son Shamsher (Arthur's twin brother), who would have turned seven on September 10.

Celina had written: "As baby Arthur’s birthday approaches on the 10th of September many different emotions overwhelm me as I remember all that we’ve been through… All that could have been …. We lost Arthur’s twin Shamsher to a hypo plastic heart and this is something that is very difficult to fathom even after 6 years.”

"Arthur often asks of Shamsher and cries for him, he has memories of him he says ( I don’t know how though) The older twins Winston Viraaj try to console and make up for Shamsher to little Arthur… They being twins understand his pain better than anyone else I guess," the post read.

The 'Miss India 2001' got married to Austrian entrepreneur and hotelier Peter Haag in 2011. They became parents to twin boys born in 2012-- Winston and Viraaj. She gave birth to a second set of twin boys Shamsher and Arthur in 2017.
