Bebe Rexha is looking back at some of her first interactions with some of music’s biggest stars.

In an interview with SiriusXM’s “The Morning Mashup”, the “Last Hurrah” singer, 29, recalled two hilarious meetings with Cardi B and Katy Perry.

While backstage at an awards show, Rexha said she ran into Perry while she was a little under-dressed, “I saw her boobs.”

“Her boobs are so nice. Her boobs are amazing,” Rexha recalled. “She was changing to go on stage and I was like ‘wow’.”

But when she met the “Bodak Yellow” rapper, another body part was the topic of conversation.

“The first thing she ever said to me was ‘damn girl, I didn’t know your a** was actually that big,'” Rexha said. “I was like, ‘Nice to meet you.’”

Later on, Rexha addressed her father’s recent comments about her Instagram. On Tuesday, Rexha posted a screenshot to social media of a text from her dad, reading, “You better stop posting stupid pornography because you make me sick.”

“I shouldn’t have done that,” she said. “He hasn’t talked to me in two weeks.”

“I think my dad always looks at me like his daughter… like a little girl… and I understand,” Rexha explained. “My dad loves me and I love him.”
