In the past, Shams had remarked vitriolically that Ahlam was 'Cholesterol,' a toxic substance. She later attempted to make up for her disrespect, but Ahlam was having none of it.
Acquaintances said that Shams's unchecked mockery was only designed to promote her new upcoming album which marks a return after an absence from the limelight for such a long spell. Especially now that Ahlam had become one of the most famous celebrities  in the Arab world, gaining noteriety from her fiascos on Arab Idol , Shams felt compelled to make some noise!
Reports mention a clash between the singers that occured three years ago. While the Gulf pair have since reconciled, the dispute reamins apparently not fully settled, nor water under the bridge.
What have you got to say about one Gulfi superstar laying into another? Why is Shams being so mean-spirited about fellow singer from the UAE?
