Embattled singer Chris Brown is struggling to deal with the public backlash following his alleged bust-up with Rihanna last month, according to his pal Tyrese Gibson.

The 'Kiss Kiss' hitmaker is facing almost five years behind bars if convicted of assaulting Rihanna during the February 8 incident, which left the 'Umbrella' singer beaten and bruised.
