Bollywood`s another real couple of  item girl Malaika Arora and her husband and brother of superstar Salman Khan  Arbaaz Khan is on the verge of divorce.  Their  18-year-old marriage seems to be ending soon.  Malaika has made up her mind about filing for divorce and she`s not listening to anyone, not even her brother-in-law Salman, whose repeated attempts to  set  things  right  between the troubled couple have come to a naught.Malaika and Arbaaz first raised eyebrows when they signed up as hosts for the reality TV show, `Power Couple`, but filmed together for barely three episodes. When they eventually agreed to appear together after much cajoling, they`d arrive in separate cars, use individual green rooms and leave separately.  Later ,  Malaika had  reportedly walked out of their Bandra home with 14-year-old son, Arhaan,  and  hired an apartment in  Mumbai.  It is reliably learned that sister Amrita and her husband, Shakeel Ladak,  and mom, Joyce Polycarp, were  recently invited to intevene  but in vein.  Malaika has  now informed Salman and the  his family  that she has been single-handedly providing for her son  financially.   Sources close to Malaika  confirm that  she is separated and will file for divorce.
