Rexha is a body-positive advocate and revealed in August that a male executive said she was "getting too old" to post such sexy pic on social media.

"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."

"To all the people tweeting mean things to me about my weight you just want a response and you will not get it," the hitmaker tweeted in June.

She followed this up with a second tweet, saying, "Unless you are completely perfect you have no f---in right to talk about anybody else’s body. The hate you breed that stems from Insecurity don’t look pretty on you."
