BEBE REXHA CLAPS BACK AT 'MALE MUSIC EXECUTIVE' WHO TOLD HER SHE'S 'TOO OLD TO BE SEXY'

Rexha, who has lent her vocal talents to hits like "Meant to Be" and "Back To You," has been outspoken about her "dirty 30" birthday after revealing in August a male executive said she was "getting too old" for the music industry.

"If I want to be sexy, I’m going to be sexy."

"I recently had a MALE music executive tell me that I was getting too old and that my brand was 'confusing,'" Rexha wrote on social media at the time.

"Because... I’m a songwriter and I post sexy pics on my Instagram and that’s not what female songwriters are [supposed] to do, especially for my age. I’m 29," she added. "I’m fed up with being put in a box. I make my own rules. I’m tired of women getting labeled as 'hags' when they get old and guys get labeled as sexy with age."

"If a man were to take off his shirt and show off his abs and rub oil all over his body, I doubt anyone would say that he’s exploiting his sexuality — and that pisses me off. So, I’m definitely going to do what I want and do what I feel."
