Attorney Michael Gilden told the New York Daily News Tuesday Lozada was seeking an end to the five-week-old marriage after the six-time Pro Bowl receiver was charged with injuring her during a Saturday altercation in Davie, Fla.
"Given recent events in my client's life, she has decided to file for divorce and move forward with her life," Gilden told the newspaper.
Johnson -- formerly known as Chad Ochocinco -- was arrested after Lozada complained to police he "head-butted" her during an argument, causing a deep laceration on her forehead.
The Miami Dolphins released Johnson Sunday and cable channel VH1 has dropped plans for a reality TV show starring Johnson and Lozada.
"I would like to apologize to everyone for the recent events that have occurred," Johnson said in a statement on his Web site Tuesday.
Lozada said in her statement, issued earlier in the day, she hoped Johnson "seeks the help he needs to overcome his troubles."
