Stevie Wonder choked back tears during an interview in which he revealed his last words to Aretha Franklin before she died.
Stevie joined "CBS This Morning" Friday and almost immediately got emotional when asked about his last real conversation with the Queen of Soul, which was about 2 months ago. Stevie -- who said Aretha couldn't talk when he visited her Tuesday -- said he told her to "say hello to my sister."
Stevie's sister died earlier this year. Reports say her decomposed body was found in her home.
Stevie revealed there were plans to do some music together ... including a duet with Aretha for a song he'd written. Aretha and Stevie were incredibly close. She covered Stevie's 'Until You Come Back to Me' and they performed it together at the Soul Train Lady of Soul Awards in 2005.
Watch the video ... Stevie gives some insight on "Respect." As we reported ... Aretha died after a long battle with pancreatic cancer. She was 76.
