Washington, Apr 1 : Actor Vin Diesel must be regretting his appearing on Jay Leno’s show, for he was left red-faced after the talk show host grilled him on his marriage plans.

The Hollywood hardman appeared on ‘The Tonight Show’ with Leno on March 30, and the witty anchor made him answer the most personal questions on his relationship with girlfriend Paloma Jimenez.

The couple has been dating for seven years, and the actor has admitted that family members are putting pressure on him to propose.

However, ‘The Fast and the Furious’ star was in no mood to reveal his intentions on US TV, and refused to discuss any upcoming nuptials on Leno’s show.

According to Contactmusic, Leno asked the actor: "When are you going to marry her?"

And an embarrassed Diesel replied: "Hey Jay, what are you trying to do? Whose side are you on? Was my mother on the show last night...? This is horrible - on national TV!" (ANI)
