Karan Singh Grover and Bipasha Basu have not confirmed their rumoured relationship, but speculations about their marriage have been doing the rounds for quite some time now. However, a latest report said that there stands a big hurdle between the rumoured love birds' marriage and that is none other than Karan's mother.

Karan's mother, Deepa Singh is not willing to accept Bipasha as her son's wife and has threatened the "Hate Story 3" actor that she would cut off ties with him if he marries the actress, according to SpotboyE. The report also added that Karan's mother is not happy about Bipasha's former relationships with Dino Morea, John Abraham and Harman Baweja.

Karan got divorced from his second wife Jennifer Winget recently. The report said that the former's mother was not happy with her as well. "After they (Karan and Jennifer) got married, she (Karan's mother) allegedly didn't enter Karan's house till the time Jenny moved out. Apparently, she also made him promise that he will not remarry without her blessings," the report said.

Karan and Jennifer got married in 2012, but had been staying separately since January 2014. Karan was earlier married to Shraddha Nigam -- 2008 -- but the duo's relationship ended in divorce a year later.

Recently, there was a buzz that Karan and Bipasha have got engaged after the actress was seen wearing a diamond ring. However, the Bengali diva soon rubbished the rumours as she took to Twitter and said, "Wait for me 2announce my wedding when I want to n if I want to.Please stop treating it frivolously."The next tweet read, "For years I have dealt with this constant discussion.Please be patient. After all it's my life:) Thank you all."
