Arriving for another stint of filming, Jennifer Lopez was spotted on the Miami, FL set of “Parker” on Wednesday (September 21).

The “Papi” singer, clad in a long dress and sweater, was escorted by a bodyguard to the set to begin readying for the long day in front of the cameras.

Coming up this weekend, Miss Lopez is set to perform at this year’s iHeartRadio Music Festival in Las Vegas on September 23rd and 24th.

Other artists who will be there include Lady Gaga, Nicki Minaj, Usher, Jay-Z, Carrie Underwood, Bruno Mars and Kelly Clarkson.

Bands like Coldplay, the Black Eyed Peas, Jane’s Addiction and Rascal Flatts will also be partaking in what’s sure to be an extravagant affair.
