Heslop signed with Polydor and recorded her second album, All for Love (1987) in the United States, but neither the album nor its 3 singles had much success. In 1989, she released the stand-alone single "Lover Don't Go", which failed to chart. Her third album, "Say It", which was slated for release in 1990, eventually was never issued as Princess retired from the music scene and moved to the USA after the death of her mother and the assassination of her brother.
From 1991 to 2003 she lived in the U.S., before returning to England in 2003. That same year she formed her own music label with her brother Donovan, OnDa Ground Music Label, which has released all her music since, and released her first single in 14 years, "Ride", with rap ensemble EEDB. A music video was also filmed which referenced her retirement.
She appeared in ITV's 2005 production Hit Me, Baby, One More Time, singing Kylie Minogue's "Slow".
In April 2014, she released her third album, The Emergence, the first in 27 years. It is the first in a trilogy of albums, the other ones titled The Passion and The One.
