Jennifer Lopez is bracing for a mega(ton) performance….

The 46-year-old Puerto Rican singer/actress has joined the roster of acts performing at the SBS network’s annual Megaton Mundial de Polito Vega, taking place on October 28 at Madison Square Garden.

Lopez is the only pop act so far on a roster that, as is traditionally the case with Megatón, features predominantly tropical and urban music.

The Megatón will also feature performances by Pitbull, veteran rappers Tego Calderon and Vico C, Cuban duo Gente de Zona and Ivy Queen.

Salsa performers include Luis Enrique, Pirulo y la Tribu, Tony Vega, Hector Tricoche and Nino Segarra, while merengue will be represented by Elvis Crespo, Grupo Manía and La Dinastía Rosario. Bachata will be present courtesy of El Torito, Bachata Heightz and Jay Ruiz.

SBS’ annual Megatón, produced by SBS Entertainment, bears the name of popular radio personality Polito Vega, who’s been on the air more than 50 years.

Vega is one of the iconic voices of Mega 97.9 FM, the top-rated Spanish-language station in the country.
