Bipasha Basu reportedly embarrassed her rumoured boyfriend Karan Singh Grover after getting drunk during a dinner date.

Bipasha and Karan recently went for a dinner date at Joss Restaurant in Santacruz, where the actress consumed some vodka and soon grabbed everyone's attention by speaking too loud, reports Absolute India.

This left Karan very embarrassed and he tried to calm his supposed girlfriend down by asking her to "behave properly", the report added.

However, Bipasha was too drunk to even pay heed to the "Hate Story 3" actor's words and carried on with her high spirit.

While the duo entered the restaurant at 9 pm, Karan and Bipasha left the venue at around 11.30 pm, and Karan apparently had a tough time controlling the Bong beauty.

Although the two are believed to be in a relationship, they never confessed to it in public. Recently, Karan was asked about his relationship with Bipasha and if they were planning on getting married in future. The actor was rather surprised to hear the question and asserted that he and Bipasha are just good friends.

Karan's last film "Hate Story 3" has done descent business at the box office and Bipasha recently appeared as the host of a horror TV show titled "Darr Sabko Lagta Hai".
