A representative for the reality star confirmed that she filed for divorce on Tuesday. Lozada also issued a statement saying Johnson "needs help."
This comes after Johnson was arrested for allegedly head-butting Lozada during an argument over the weekend. The fight reportedly occurred after Lozada questioned Johnson about a receipt for condoms that she found.
After Johnson was released from jail Sunday, he received word that the Miami Dolphins released him from the team.
