Jennifer Lopez and Shakira sizzled onstage at the Super Bowl halftime show in a high-powered, raunchy extravaganza.

And while the show and both singers have been lavished with praise, it has launched fierce debate over whether Janet Jackson deserves an apology for the response to her revealing performance 16 years ago.

In the final seconds of Jackson's 2004 set, Justin Timberlake famously tore off part of her clothing and exposed her nipple, in an incident which was ridiculed and later credited for hurting the singer's career.

JLo and Shakira co-headlined the world's most watched stage at the NFL championship game between the Kansas City Chiefs and San Francisco 49ers in Miami, Florida today, with a 12-minute medley of their biggest hits.

Kicking off with an explosion of fireworks, Shakira hit the stage first surrounded by dancers dressed in frilly red, opening with her electrifying song She Wolf, before breaking out the electric guitar.

One of her biggest claims to fame, Shakira's belly-dancing was on full display as she performed her number one tune, Wherever, Whenever.

She wrapped her solo set by crowd surfing during Hips Don't Lie.

But it was JLo's set that really stunned, featuring more than 130 dancers as the 50-year-old exploded onto the stage with a sexy solo performance.

Opening with Jenny From The Block, JLo made a grand entrance on an illuminated pole before belting out Ain't It Funny and Get Right, wearing a black leather figure-hugging suit.

She then had a costume change mid-performance, switching into a barely-there silver piece as the singer showed off her impressive pole dancing skills, in what was no doubt one of the set highlights.

Shakira then joined JLo for an energised compilation of their respective songs, Let's Get Loud and Waka Waka (This Time For Africa), capping off their epic show shaking their famous assets in sync on a platform.

The performance has already been met with widespread applause, with P!nk and Lagy Gaga taking to Twitter to praise the pair.

Earlier, it was revealed that some lucky punters at the stadium received light-up wristbands and notes, instructing them to hold them up high for "an important part" of the halftime show:

This year's show was produced by Jay Z's entertainment agency, Roc Nation.

The halftime show often generates more buzz than the game itself.

Katy Perry's 2015 performance remains the most viewed halftime show in history, with 120.7 million TV viewers, with Lady Gaga's 2017 show coming in second with 117.5 million, the star eclipsing the game's viewership.

Maroon 5 performed last year in what was widely panned for being boring, raking in 98.2 million viewers, its lowest in a decade.

The NFL announced in September the two Latina artists would be performing together for the first time in the event's history.

"Ever since I saw Diana Ross fly off into the sky at the halftime show, I dreamed of performing at the Super Bowl," Lopez said after the announcement.

"And now it's made even more special not only because it's the NFL's 100th season, but also because I am performing with a fellow Latina."
