The swanky surgeon has made multiple trips to Australia to be with Alex, including flying Down Under to spend Christmas with the glamorous nurse and her family.

Alex has also made several trips to New York to be with Sachin.

The Harvard-educated doctor is one of the top names in his field and was trained in Plastic and Reconstructive Surgery at the prestigious Johns Hopkins Hospital.

He went on to establish his own clinic LUXURGERY in 2014, which offers many of his own signature procedures, including the Tubeless Tuck.

The popular clinic is located on New York’s famed Fifth Avenue in Manhattan.

Sachin was the first plastic surgeon in New York to inject Kybella following its FDA approval.

He has also featured in The New York Times and the New York Post as well as on multiple TV shows, including The Doctors and The Meredith Vieira Show.
