BROOKLYN - Jenny's block may be in the Bronx, but Jennifer Lopez's new cellphone store is in Brooklyn.

The superstar made a special appearance at a block party to celebrate the opening of "Viva Movil" in Brooklyn. The shop offers cellphones and even a kid zone allowing parents to shop children-free.

Fans flooded Flatbush Avenue for the party, which included face painting, balloon artists, food trucks and plenty of fun.

J. Lo is opening another new location in Queens over the weekend.
