( CNN ) -- Christine Beatty , chief of staff for former Detroit Mayor Kwame Kilpatrick , pleaded guilty Monday to charges stemming from their text-messaging sex scandal case and will serve four months in jail , according to the Wayne County prosecutor 's office . Under a plea deal , Christine Beatty , shown in August at an arraignment in Detroit , will serve five years probation . Beatty pleaded guilty to two counts of obstruction of justice , according to Maria Miller , the prosecutor 's spokeswoman . Charges of perjury and misconduct against Beatty will be dropped as part of the plea arrangement , she said . Beatty agreed to a plea arrangement under which she will serve five years probation -- the first 120 days to be served in jail -- and pay a $ 100,000 fine , `` based on [ Beatty 's ] ability to pay , '' Miller said . Beatty will begin serving her jail sentence on January 5 , when she will be formally sentenced , Miller said . Kym L. Worthy , prosecuting attorney for Wayne County , released a statement saying she is `` very pleased that this defendant admitted her guilt . '' `` We live in an age where greed and protecting one 's secrets is glorified and accepted , '' Worthy said . `` Now the city of Detroit , the region and the state of Michigan can truly begin to move forward when this ugly chapter in Detroit 's history is put to rest . '' In September , Kilpatrick resigned as mayor and pleaded guilty to two felony obstruction of justice charges stemming from his efforts to cover up his relationship with Beatty . Like Beatty , Kilpatrick was sentenced to five years probation with the first four months to be served in jail . He is serving that sentence in the Wayne County jail . At the time of his sentencing in October , the judge in the case called Kilpatrick `` arrogant and defiant , '' particularly for a televised speech that aired hours after Kilpatrick entered his pleas . `` That night , the community expected to hear a message of humility , remorse and apology , '' Wayne County Circuit Judge David Groner said at Kilpatrick 's sentencing . `` Instead , we heard an arrogant and defiant man who accused the governor , among others , for his downfall . '' In addition to his jail and probation sentence , Kilpatrick must also pay the city of Detroit $ 1 million in restitution , and forfeit any future pension . Initially , Kilpatrick was accused of blocking a criminal investigation into his office and firing a police deputy to cover up an affair with Beatty , then his chief of staff . When that deputy , Gary Brown , filed a whistle-blower suit , Kilpatrick and Beatty denied under oath that an affair had taken place between them . Text messages that contradicted Kilpatrick 's and Beatty 's denials of an affair were made public in January by the Detroit Free Press , and county prosecutor Worthy charged Kilpatrick and Beatty with multiple counts of perjury , obstruction of justice and misconduct in office . The most serious charges would have carried a maximum penalty of 15 years in prison upon conviction . Beatty resigned her post after the text messages were made public . Kilpatrick initially refused to resign after the scandal broke , and Michigan Gov . Jennifer Granholm called a hearing on whether she should remove him from office at the request of the Detroit City Council . Granholm adjourned those hearings after Kilpatrick pleaded guilty and resigned in September .
