Winning: Jennifer Lopez announces 19 additional 'All I Have' shows...

Due to popular demand and SIX sold out shows in January, Jennifer Lopez has added 19 new dates to her 'All I Have' residency in Vegas.
Another day, another slay!  Last night marked the end of her first run of Vegas shows and she celebrated with the announcement. Jen has dates through May, June, July and August and her manager Benny Medina reportedly told a fan at her 'All I Have' meet and greet that she's dropping a new single in April. Makes sense! The additional performances go on sale to the public beginning Friday, February 12th at 10AM PT and can be purchased via Ticketmaster.
