Atlantic City, NJ, September 28, 2007 – The J. Lo and Marc Anthony joint concert tour lifted off at the Trump Taj Mahal in Atlantic City on Friday night, and we sent a spy. 

Marc Anthony opened the show with a 90-minute hip-swinging set that had the crowd captivated.  Next, Jennifer Lopez did a solo set of about an hour.  While she clearly doesn’t have the vocal power of her hubby, J. Lo’s set was slickly produced and professional.  For a finale, the couple did two songs together, ending each with a kiss.  (Awe.)

Lopez changed outfits at least three times, and her voluminous Roberto Cavalli costumes and less-than-strenuous dance moves gave rise (again) to speculation that she is pregnant.  However, some in the music biz surmised that, at 38, Lopez is just too old to break into really difficult dance routines.
