Nicki Minaj at Summer jam

Rapper Meek Mill brought his girlfriend, ropper Nicki Minaj, onstage at the Summer Jam concert series at MetLife Stadium in East Rutherford, NJ Sunday night.

The 28-year-old Philadelphia native told the crowd his album is dropping next month. Mill performed a short set before introducing the petite 32-year-old rapper. Minaj performed 2 songs and left the stage — but not before she and Mill exchanged I love you’s.

Mill also brought out rapper Future.

If you’re wondering why Nicki wasn’t originally on the bill, an insider says she demanded way too much money.

Not surprisingly, most of the action took place outside the stadium.

WABC reports New Jersey police fired tear gas canisters into an unruly crowd who couldn’t get into the sold-out stadium.

Thousands of hip hop fans, some of whom paid $1,000 for scalped tickets, were trapped outside the gates, unable to access the concert headlined by Kendrick Lamar, Trey Songz, Big Sean and Chris Brown.

Ticket holders jumped the fence and clashed with security. Roving bands of youths threw bottles and other debris at the police line. After police fired tear gas, the crowd dispersed and order was eventually restored. WABC reports numerous arrests.

NY radio station Hot 97, which organized the annual concert series, promised refunds to ticket holders whose tickets were not scanned at the gates.

Ticket holders who purchased their tickets from scalpers are out of luck.
