Singer/songwriter Melissa Etheridge is asking a judge to install a smoking ban around her two young children after her ex-lover allegedly burned one of the tots with a cigarette by accident.
Etheridge and actress Tammy Lynn Michaels ended their seven-year relationship in 2010 and they've been locked in a war of words over their five-year-old twins Johnnie and Miller ever since.
Earlier this week Tammy launched a legal battle against the Grammy winner, seeking a hike in child custody payments and accusing Etheridge of brainwashing the toddlers into being rude to her.
And now the "Come to My Window" hitmaker has fired back with her own legal documents, requesting a smoke-free court order to protect the well-being of their two kids.
The singer also used her latest court documents, obtained by TMZ.com, to dismiss Michaels' recent claims she lacked maternal instinct, calling her ex "angry and vindictive".
The former partners are heading back to court next month for the latest round in their custody battle.
