Rosemary Wahu Kagwi is an R&B artiste from Kenya.

While she was a student at Precious Blood Secondary School, in Riruta, she wrote her first song called 'Showers of Blessings' (with a friend) as a tribute to God for the national academic success that the school enjoyed. The song is still part of the schools hymnal collection.

She worked in the entertainment industry and used the money to pursue her university education at the University of Nairobi, studying for a Bachelors degree in Mathematics.

Her first song 'Niangalie' drew the attention of renowned CBN presenter Victor Oladokhun, who aired it on his 'Turning Point' program. Her second song 'Esha' was a fusion of English Swahili and Kikuyu based on a traditional Kikuyu folk song, and inspired by the late Brenda Fassie. She also came out with 'Liar', 'Kibowow' and 'Sitishiki'. She launched an album, Liar, in 2004.

In 2004, she married longtime beau David Mathenge (popularly known as Nameless) who was also on the Ogopa DJ's label. They have one child, a daughter who was born in 2006. She also acted in a leading role in the popular television show, Tazama on KTN.
