Mario is in hot water. The 24-year-old was arrested this morning in Baltimore for second degree assault. Earlier this week, after flying into a rage, the platinum-selling R&B singer allegedly assaulted his mother Shawntia Hardaway, with whom he shares an apartment.

According to TMZ, police claim that Mario, whose real name is Mario Dewar Bennett, was "throwing and damaging property," which they later discovered to be a broken china cabinet and shattered mirror. Police also state that Mario then pushed Shawntia, a former heroin addict, with his hands and forearms "eight feet into a living room wall, where Ms. Hardaway hit her head on the wall" where an imprint was made upon impact.

This isn't the first time that Mario, who was released this morning on $50,000 bond, has been involved in a physical altercation. This past July, the singer punched a sound engineer at the 16th Annual Rochester MusicFest after he cut off his microphone and turned the lights on when his set ran too long.

Mario, who most recently appeared as a contestant on Season 6 of 'Dancing With the Stars,' released his fourth album 'D.N.A.' in September 2009. He is currently working on his club-oriented fifth LP.
