Andrea Martin, the singer-songwriter who wrote songs for many R&B and Pop artists, has died at the age of 49.

Martin’s death was announced in a statement shared to her Instagram Story on Monday.

“Dear Family and Friends, it is with a heavy heart we inform you of the passing of our beautiful Andrea Martin also known as ‘Annie,’ ” the statement read. “Andrea will always be remembered for her passion and dedication to her family and friends. Her impact will continue to be felt and heard for a lifetime.”

“We thank you in advance for your condolences, love, compassion and understanding during this time,” the message continued. “Please limit calls as we are trying to finalize arrangements at this time, Once finalized, we will be sure to post arrangements.

“Forever a legend. April 14 – September 27.”

A cause of death hasn’t been revealed.

Martin’s longtime writing partner Ivan Matias — with whom she penned hits like En Vogue‘s “Don’t Let Go (Love), SWV‘s “You’re the One” and Angie Stone‘s “Wish I Didn’t Miss You” — also confirmed the death in an Instagram Story post of his own.

During her songwriting career, Martin also wrote songs for Toni Braxton, Leona Lewis, Melanie Fiona, Sean Kingston, Fantasia Barrino and Jennifer Hudson.

She also received credit for writing Monica‘s 1995 hit “Before You Walked Out of My Life,” which spent two weeks at No. 1 on the Billboard Hot R&B Singles chart.

Martin was also a gifted singer and released her debut album, “The Best of Me”, in 1998 under Sony’s Arista Records.

 At the 2011 ASCAP Expo, Martin shared her experience as a songwriter and said that the most important aspect of making music is speaking from the heart.

Thank you for the many hits, Queen. Rest in peace.
