Irish Grinstead, a member of the R&B trio 702, known for its 1999 hit “Where My Girls At?,” died on Saturday evening at the age of 43, according to her sister.
A cause of death was not immediately available, but the group announced in December that Irish Grinstead was taking a “medical leave of absence due to serious medical issues.”
LeMisha Grinstead, Irish Grinstead’s sister and bandmate, said in an Instagram post announcing her death that she had “had a long battle and is finally at peace.”
“That girl was as bright as the stars! She was not only beautiful on the outside, but also within,” LeMisha Grinstead wrote. “Sharing the stage with her was a joy I will cherish for the rest of my life!”
The Grinstead sisters and Kameelah Williams comprised 702, which was named for the telephone area code in Las Vegas, where they were from.
“Devastated & heartbroken,” Ms. Williams wrote in an Instagram post on Sunday. “There’s a lot I want to say, but there’s no way to say what your heart hasn’t fully accepted.”
The group’s 1996 debut album, “No Doubt,” included a song called “Steelo,” featuring Missy Elliott. A version of the track was the theme song for the Nickelodeon show “Cousin Skeeter.” The song was also sampled in a 2019 dance music hit produced by Diplo.
“Irish May your beautiful soul Rest Peacefully in the arms of the Lord,” Ms. Elliot wrote in a post on X, formerly known as Twitter, on Sunday. “Multitude of prayers for the entire Grinstead family.”
702’s defining hit was “Where My Girls At?,” which peaked at No. 4 on the Billboard Hot 100 chart in 1999, according to Billboard.
As news of Irish Grinstead’s death circulated, fan tributes flooded social media in the form of music video clips featuring Irish Grinstead dancing alongside her sister and Ms. Williams in distinctive ’90s glam and choreography.
The group released its last album, “Star,” 20 years ago but continued to perform shows, with several scheduled through the rest of this year.
Irish Grinstead’s twin sister, Orish Grinstead, died in 2008, according to IMDb.
