Arbaaz Khan was spotted at sister-in-law Amrita Arora Ladak's birthday celebrations in Dubai.

However, Malaika was missing from the scene. Meanwhile, reacting to his troubled marriage rumours, Arbaaz made a dubsmash on the chartbuster 'Kuch Toh Log Kahenge' on Instagram.

He captioned the video, "Some people need to mind their business, stop talking.... and concentrate on their own miserable lives." Not that this will stop speculations.
