MEL GIBSON's baby mama and legal combatant OKSANA will not only tell ALL to OPRAH but she will reveal her talent for tinkling on national TV.
Tinkling the piano keys, that is.
RadarOnline.com reports Oksana Grigorieva agreed to spill all  about Mel Gibson to Oprah Winfrey -- on the one condition: she could sing and play the piano too.
"Oksana will be performing on the show in addition to answering questions about the scandal," an insider divulged.
"She is proud about her musical talents - as she should be - and she wants to make sure that her daughter, Lucia, can look back at her mom when she grows older and also be proud."
