Arjun Kapoor suffered a lot of pain at the hands of Katrina Kaif 

Well not the assumed heart-ache, as one would guess it to be. Arjun Kapoor is Katrina's rakhi brother and hence, might have never considered being paired in films opposite each other.

Once she offered to thread his eyebrows, and he more than happily agreed to get it done as saying no to a beauty would be unfair. However, he suffered lots of cuts and was in pain ever since.

Arjun does not even recall why she threaded it for him, but we are sure it was sweet pain.
