Mumbai: Singer Mika Singh raised a few eyebrows with his tongue-in-cheek humour at the music launch of the upcoming film 'Happy Bhag Jayegi', in which he has sung a song. Mika has sung 'Gabru Ready To Mingle Hai' in the film with Neeti Mohan. At the music launch of the film, before he performed the song with Neeti, he said: "It's my second song with Neeti, before this, it was 'Taang Uthake' (lifting your leg), abhi sab kuch uthake aayega (this time everything will be lifted)." 'Gabru Ready To Mingle Hai' is also composed by Sohail Sen, who had composed 'Taang Uthake' from 'Housefull 3'. Mika also kept wrongly pronouncing lead actress Diana Penty's name as Deena or Deana throughout the event. When the team of the film, including actors Ali Fazal, Jimmy Sheirgill, Diana, producer Krishika Lulla, director Mudassar Aziz were arranging themselves for a photo-op, Mika said: "I want that Deena you come in the centre. (When corrected) Diana Penty and Mika Kaccha (underwear), it's a good name." He also said: "Actually my English is very hi-fi, so whenever I take Deena's name, it is like Deana or Deena. But Happy (her character in the film) is better, then no worries at all. "So I am a big fan of Happy, four years ago when her film had released, it was wonderful, and she had matched up with Saif Ali (Khan) and Deepika (Padukone). Already 'Cocktail' was a big film and today is a big day that even I have sung for her, so she is very lucky." He also kissed Diana on the hand and later danced with her. He said: "About Diana, I want to say she is so beautiful and sweet, and every man would want that he gets married to a girl like Diana because she is beautiful, gorgeous, we all love her." He quipped: "I have brought a ring and if it was not expensive, I would have definitely given it to her." 'Happy Bhag Jayegi' will be released on August 19.
