Wireless Festival has announced that Cardi B will no longer headlining following her pregnancy news last week.
After the show she also tweeted: "I started winning when the whole world was doubting on me! think imma lose with my little baby counting on me?"
The 25-year-old has since pulled out of Wireless Festival in London. The festival sent her its best wishes on Instagram and confirmed she would not be performing.
"Huge news over the weekend! Congratulations to @iamcardb!" they wrote. "Unfortunately this means she won't be performing at Wireless this year."
Organisers said there would be an announcement on 12 April which looks set to reveal a replacement.
The festival was criticised after it revealed its lineup after critics pointed out the glaring lack of female artists on the billing.

Paul Pacifico, CEO of the Association of Independent Music, called the lineup "absurd".
"Half the population are female, half the people attending the event are going to be female - it seems absurd that Wireless wouldn't programme a schedule that was a bit more balanced," he said.
Wireless said it had no comment on the response to the lineup. With Cardi B's departure, the lineup currently features just two women - Mabel and Lisa Mercedez - among the 37 acts announced so far for the festival.
