Simone Biles' Biological Mom Speaks ... 'I'm Sober & I Love Her'

The biological mother of Team USA gymnast Simone Biles says she's clean, sober and has a loving relationship with her daughter ... and is sick of being painted as an addict.

Simone's story is pretty well-known ... she was put in foster care when she was 2 because her mother struggled with substance abuse. Simone was eventually adopted by her grandparents.

TMZ Sports spoke with Shanon Biles who says she's been sober since 2007 -- and is proud of the fact she reestablished her relationship with Simone.

Shanon says she does have a beef with her father -- saying he was insensitive about the way he described her battle with addiction during an interview with NBC.

"He could have been more classy about it."

As for Simone, Shanon says she's incredibly proud of her daughter and has supported her for years -- in fact, she showed us a pic of the two of them with Gabby Douglas back in 2014.

"I just want to say I love you Simone ... I'm so proud of you! Go Team USA and I'll talk to you and see you when I can!"
