On the third week of this season’s Celebrity Fit Club, Bobby Brown finally faced his fears — no, not of ex-wife Whitney Houston — but he handled his crippling horror of hounds and heights. The singer impressed the VH1 series’ resident life coach, Rhonda Britten, when he completed a challenge with snarling dogs and later made it to the very top of a rock-climbing wall. “I think Bobby was the most willing this week to come clean with himself about his fears. He definitely faced more things this episode than anyone else,” Rhonda tells In Touch. The most shocking incident with the infamous R&B star, however, involved a bottle of vodka. After confessing to drinking in last week’s episode, Bobby, who battled substance abuse in the past, disposed of his alcohol in an effort to stay sober and focus on his fitness goals. “It was huge. This could give him more confidence and help him be more disciplined. Now we’ll see if that translates into weight loss,” Rhonda added. Watch Celebrity Fit Club on Mondays on VH1, and catch Rhonda on her Fearless America Tour, stopping next on February 25 in Atlanta, and on February 27 in Orlando, Fla.
