Neil, 50, is accused of poking his finger into the chest of Alicia Jacobs in a casino comedy club late March 24. He's also accused of cursing and pointing or poking at Jacobs' friends, John Katsilometes and Patricia McCrone.
Neil's lawyer, David Chesnoff, said the singer intends to plead not guilty to the battery and disorderly conduct charges. He's due May 2 in Las Vegas Justice Court.
"There are two sides to every story, especially when there are issues surrounding relationships," Chesnoff said. "We are looking forward to a trial on the matter."
Neil could face up to six months in jail and a $1,000 fine on each charge.
Jacobs, a 39-year-old Las Vegas entertainment television reporter, showed police a bruise that she said came from the finger-poke. She said Tuesday she worries about being in the same room with Neil, with whom she told police she had a seven-month relationship that ended in early March.
Neil was freed from Clark County jail Feb. 25 after serving 10 days for driving drunk last June near the Las Vegas Strip. He also was fined $585 and ordered to serve 15 days on house arrest as part of a plea deal that avoided trial in the case.
