The song, he said, will be out Friday.
"Right now I am shooting a song with her (Kareena) for 'Singham 2'. I am doing a song with Kareena, Ajay Devgn and Honey Singh. It's a promotional song and will be launched Aug 1," the 47-year-old said here at the Lakme Fashion Week (LFW) press meet.
Malhotra has been a part of the fashion and film industry for a long time and reminisced his association with the glamour industry.
"Just this morning I was talking to Kareena and she said 'My god, I have been working for 15 years.' I told her that next year I will complete 25 years in the film industry and ten years to my label. My association with Lakme will also be 14 years old," the designer said.
Malhotra's bridal 'Gloss' collection will be showcased at the grand finale of LFW, scheduled for Aug 20-24. Kareena will be his showstopper.
