The much-anticipated Tina Turner HBO documentary Tina is finally here. Though fans have various renditions of her life story (the Angela Bassett-staring biopic What's Love Got to Do With It, the Broadway musical Tina: The Tina Turner Musical, and Tina's own autobiography I, Tina), the new documentary captures her ability to reclaim her life and career in a way that's especially powerful, inspiring, and sometimes painful to watch.Following Tina after she walks away from her abusive relationship, we see how she strives to re-invent herself.

It's also thanks to one person who stood by her side from the very beginning: her assistant and friend, Rhonda Graam.Who was Rhonda Graam?Rhonda Graam was a huge fan of Tina's back in the '60s when Tina was still performing with former husband Ike Turner. She was eventually hired as her assistant in 1964, and stayed on to work for Tina after the musician and Ike got divorced.
