Tamar Estine Herbert (nee Braxton, born March 17, 1977), professionally known as Tamar Braxton, is an American singer, television personality and actress. Braxton had her first big break in music in 1990 as a founding member of the American R&B singing group The Braxtons, formed with her sisters. The Braxtons released their debut album, So Many Ways, as a trio in 1996.

Tamar Estine Braxton was born in Severn, Maryland on March 17, 1977 to Michael and Evelyn Braxton. The youngest of the Braxtons' six children, Tamar started singing as a toddler. The Braxton children would eventually enter in their church choir, where their father Michael Braxton was a pastor. Sisters Toni, Traci, Towanda, Trina, and Tamar Braxton signed their first record deal with Arista Records in 1989. In 1990, they released their first single, "Good Life". "Good Life" was unsuccessful only peaking at No. 79 on the Billboard Hot R&B/Hip-Hop Singles chart. At the time of the single's release, the members' age differences created a problem with marketing. Subsequently, The Braxtons were dropped from Arista Records.  In 1991, during a showcase with L.A. Reid and Kenneth "Babyface" Edmonds, who were in the process of forming LaFace Records, Toni Braxton, minus her four sisters, was chosen and signed as the label's first female solo artist. At the time, the remaining members were told that LaFace was not looking for another girl group since it had just signed TLC. After Toni's departure from the group, the remaining Braxtons members became backup singers for Toni's first tour, music videos, and promotional appearances. Traci, Towanda, Trina, and Tamar were featured in the music video for Toni Braxton's third single, "Seven Whole Days", from her self-titled debut album.  In 1993, LaFace Records A&R Vice President, Bryant Reid, signed The Braxtons to LaFace. However, the group never released an album or single for the label. When Reid moved on to work for Atlantic Records, he convinced executives at LaFace to allow him take the group to Atlantic also. It was reported in Vibe magazine that in 1995, Traci Braxton had left the group to pursue a career as a youth counselor. However, it was not confirmed until a 2011 promotional appearance on The Mo'Nique Show, that Traci was not allowed to sign with Atlantic because of her pregnancy at the time.  In 1996, Tamar, Trina, and Towanda returned with a new album entitled So Many Ways, which peaked at No. 26 on the Billboard R&B/Hip-Hop Albums chart. At the time of its release, Reid told Billboard Magazine, "I had a vision for them then that was about young sophistication with sex appeal." The trio also performed a remixed version of "So Many Ways" with rapper Jay-Z on September 9, 1996 at the Soul Train Lady of Soul Awards. So Many Ways went on to peak at No. 83 on the Billboard Hot 100 chart and number 32 on the UK Singles Chart. Braxton and her fellow The Braxtons members served as the opening act for Toni Braxton on the European Leg of her Secrets Tour in 1997. The Braxtons decided to part ways as a group after lead singer Tamar Braxton left to pursue a solo career with DreamWorks Records in 1998.
