Vanessa Bryant was reportedly tipped off about her husband Kobe's extra-marital affairs by fellow basketball wives.

According a "secret underground society of trained spies," otherwise known, as the wives of NBA stars, are responsible for informing Vanessa about her husband Kobe's alleged extra-marital dalliances, Fox News reported.

Sources claimed that Bryant's teammates "were blabbing to their women about the superstar's exploits" and, in turn, the wives told Bryant's better half about her husband's affairs.

Despite swearing to secrecy to their husbands, the wives of NBA stars "all share information about other guys around the league" as a sort of insurance policy, so that information "will get back to them if their man ever steps out."

Vanessa Bryant had filed for divorce on Dec. 16 citing "irreconcilable differences."
