Talk about opening up old woundsJ Lo is being forced to testify in the infamous night club shooting case against Diddy:

Jennifer Lopez has been subpoenaed to testify in a lawsuit filed against hip-hop mogul Sean C****s over his involvement in a 1999 New York club shooting. The Latina was dating C****s at the time of the incident, and was present at the now-defunct Club New York when shots were fired in the venue on 27 December 1999, injuring two people.
C****s rap protege Shyne, real name Jamal Barrow, is currently serving a 10-year jail term after he was found guilty of assault, reckless endangerment and gun possession in the trial following the shooting. The rap heavyweight was arrested for various charges including weapons violations, but was acquitted of all counts.

However, both C****s and Shyne are currently fighting a $130 million (GBP65 million) civil suit filed by victim Natania Reuben, who was shot in the face during the incident.
C****s completed his deposition in the case in March (08), but now Lopez must reveal all she knows at an upcoming deposition after being served by Reubens lawyers last week (ends20Jun08). She was not called as a witness in the 2001 criminal trial and split from C****s shortly afterwards.
A judge will soon be required to decide whether Shyne acted alone or as part of C****s Bad Boy collective - the record label the hip-hop giant founded in 1993 - before the case goes to trial.
If both C****s and Shyne are required to stand trial, it will be up to a jury to decide who should take responsibility for the shooting.
Shyne, who did not testify during the criminal trial, may be required to take the stand and testify about the incident. He is currently incarcerated at the Clinton Correctional Facility in New York State, and could be released as early as next year (09).
