Bobby Brown claims Tupac had an affair with Whitney Houston while still married

Bobby Brown has claimed his ex-wife Whitney Houston and Tupac had an affair.
The New Edition star has penned a memoir, titled Every Little Step, in which he alleges his late ex and the late rapper got together after they worked together - while Whitney and Bobby were still married.
US Weekly released several extracts from the memoir, including a claim that Whitney also had a lesbian affair with her longtime assistant and friend Robyn Crawford.
Meanwhile, Whitney's Houston's mother Cissy Houston has slammed the singer's ex-husband Bobby Brown over his recent comments about her daughter.
He claimed he broke tradition on his wedding day before marrying the I Will Love you singer to discover her snorting a line of cocaine.
The R&B singer also claimed he and Whitney would spend hours a day locked in a room in their mansion doing drugs while a nanny cared for their Bobbi Kristina.

Hitting back, Cissy says she's disappointed with her former son-in-law's "disturbing" drug allegations.
Speaking to People magazine, she said: "Last night I saw Bobby Brown's interview with Robin Roberts. It was disturbing."

She continued: "There is no value in my challenging all of his statements – point for point – such as his assertion that he 'had money' when he married Whitney or that anyone in my family said he started Nippy on drugs. No one blames Bobby for that.
"However, I must say that his story of seeing her do drugs for the first time on their wedding day is untrue (Donna Houston, Robyn Crawford and I were with Nippy the whole time before the ceremony), and more importantly, it forever casts a shadow over one of the most important days of her life."
