Rumors of strained relations have dogged the couple since December last year, but they managed to hang on because Sushmita's adopted daughter Renee is reportedly close to Menon.
The two have not been seen together for the past three months now.
It is believed that cracks first appeared in the couple's relationship after 31-year-old Sushmita invited ex Randeep Hooda, who too is close to Renee, to party that Manav hosted to celebrate Sushmita's birthday.
