J. Lo gets real

Jennifer Lopez is getting into the reality TV business.

Lopez’s production company, Nuyorican Productions, is teaming with 44 Blue Productions for a hiddencamera series they’re calling “Relative Chaos.” In the series, which will be executiveproduced by Lopez and Simon Fields, families will be “punked” by “the raw comedy and high drama” when relatives come to visit (and we all know how unsettling that can be).

“Relative Chaos” will be shopped to the networks (broadcast and cable) in the next few weeks.
