Nicki Minaj is struggling to sell tickets to the second U.S. leg of her Pink Friday 2 World Tour.

The tour opened at a sold out arena in Oakland, California in March. After the successful first U.S. leg, Nicki took the tour overseas in May.

The tour grossed over $34.9 million from the first 17 shows alone, according to DailyMail.com.

But now Nicki is having difficulty selling tickets for the second leg of the U.S. tour.

Seating charts for the opening night in Philadelphia, Pennsylvania, on September 4 show that not one section of the venue has sold out.

via DailyMail.com — “And that’s not the only one. In fact, thousands of seats are still up for grabs at pretty much every show on the upcoming leg, which will span across 22 cities and end in Elmont, New York, on October 11.

After the tour was announced as “the most successful tour by a female rapper in history” in April, Nicki took to social media to celebrate.

It was also revealed that the hitmaker had become the female rapper with the most concerts earning more than $2 million in ticket sales each.

“We made female rap history as of today with how many sold-out shows and how many shows that have grossed over $2 million,” she said in a video uploaded to her Instagram at the time.”
