Hot 97's 2014 Summer Jam is infamous for bringing out surprise guests. Every set throughout the event featured a surprise artist who shared the spotlight with the headliners at Metlife Stadium in New Jersey on Sunday (June 1).

Wiz Khalifa kicked it off by bringing Snoop Dogg during his set for a rendition of 'Next Episode.' Naturally, the two stoners went into 'Young, Wild and Free,' which got everyone to their feet. Wiz also performed '23,' 'Work Hard, Play Hard' and ended his set with 'We Dem Boyz,' which sounded extra rock and roll with a live band playing behind him.

More surprise guests continued with the Roots as the Philly band brought out the LOX, M.O.P. and Black Sheep who reminded fans what 'The Choice Is Yours' sounded like live.

R&B hunk Trey Songz, who brought out Ty Dolla $ign to perform 'Paranoid (Remix),' brought the sensuality for the ladies with '2 Reasons,' 'Be Where You Are,' 'Neighbors Know My Name' and 'Na Na.' He also made sure to pay homage to Chris Brown by performing 'Loyal.'

Although Breezy wasn't at Summer Jam since he was in jail up until Monday morning (June 2), it seemed that his presence was felt during Sevyn Streeter and Lil Wayne's set as they both separately performed renditions of 'Loyal.'

Meanwhile, Nas didn't disappoint with his performance of his 1994 debut album 'Illmatic,' which is celebrating its 20th anniversary.

"It's been 20 years since this album came out," he told the crowd. "I went to the first Summer Jam. 1994. It was beautiful."

During his set, the Queensbridge MC brought out Meek Mill who performed his new track, 'I Don't Know (Suicidal),' with Paloma Ford. Nas also invited French Montana who performed 'Ain't Worried 'Bout Nothin.'

Nas finished his 'Illmatic' set and then moved into a rousing rendition of 'Hate Me Now.' But just when we thought it was over, 50 Cent sauntered onstage to perform a few of his hits.

However, Fif didn't do it alone. His fellow G-Unit members Lloyd Banks, Tony Yayo and Young Buck reunited onstage.

Unfortunately, there was a fight that went down while 50 was performing, which increased security on the already overcrowded stage. While no one really knew what happened at that moment, the show went on with Yo Gotti joining Fif onstage for 'Don't Worry About.' Although the audience was down for this G-Unit reunion, Hot 97 personality Ebro signaled for him to pull the plug and his mic was eventually turned off.

New York's reigning rap queen Nicki Minaj graced the the stage, and it seems like the show turned into one big pop concert complete with the fog and lights.

Performing hits like 'Monster,' 'Did It On Em' and Beez In the Trap,' the Queen Barbz had everyone focusing on her track record of making hits. After doing her version of 'Boss Ass Bitch,' Minaj performed her new single, 'Pills N Potions.'

Knowing she was scheduled to have friends join her onstage, everyone cheered when Young Thug, Soulja Boy and finally Drake and a shirtless Lil Wayne.

Finally, DJ Mustard was the actual show closer. "The party ain't over," he announced. "If you got love for the West Coast, put your W's up."

DJ Mustard didn't do his set alone and brought Ty Dolla $ign to perform 'Paranoid.' Summer Jam Festival 2013 alum Kid Ink performed 'Show Me' while A$AP Ferg brought the house down with 'Work' and 'Shabba.'

Bompton rhymer YG came through to perform 'My N----,' and Young Jeezy went into his track 'R.I.P.' With the energy still alive from those who were still in the stadium, DJ Mustard ended his set with his new single, 'Down on Me.'
