Rihanna put on a blow out performance at the Rock In Rio Festival in Brazil over the weekend that marked her return to the event for the first time since 2011. She closed the festival with a 24-song set that kept her on stage in front of a huge crowd well past midnight.

Tickets for her show sold within 57 minutes, a sales record for Rock In Rio, according to the festival’s Web site.

Among many of her hits, Rihanna included songs of her next album R8, wowing the audience. It was estimated to number between 80,000 and 100,000 fans.

The festival was held at the Cidade do Rock (the City of Rock) in Rio’s Barra da Tijuca.

Afteward, the 27-year-old pop diva was spotted partying well into the morning with gal pal, and rumored flame Cara Delevingne, the UK model and socialite.

Rihanna and Delevingne were a hot item over the Christmas and New Year’s holiday earlier this year before going their separate ways. They were rumored to be lovers.

Most recently, Delevingne, who is openly bisexual, has been dating singer St. Vincent. But the fact that she was spotted with Rihanna in Brazil suggests that union may be over.
