A lot of couples broke up on Monday's episode of "Love & Hip Hop: Hollywood." On the VH1 show's fifth episode, titled "Mum's the Word," Miles and Milan hit a rough patch, Princess Love dumped Ray J and Nia Riley got into a fistfight with Soulja Boy's "side chick" Nas.

The episode started with Moniece Slaughter and her mom trying to mend their relationship, and her mom asked to meet Moniece's boyfriend Rich Dollaz. At first, Rich was hesitant to meet his girlfriend's mom but eventually agreed. The dinner, however, did not go smoothly and Rich and Moniece's mom got into a disagreement after she brought up Rich getting arrested for allegedly not paying child support.

Meanwhile, Soulja Boy and his girlfriend Nia have been going through some relationship troubles ever since a rapper named Nas started telling people she was secretly dating the “Crank Dat” rapper. Nia and Nas confronted each other in a previous episode, but things got violent on Monday's show when Nas attacked Nia at a bar.

Soulja Boy decided he wanted his girlfriend to sit and talk with Nas so they could all work out their issues, but the meeting took a quick turn for the worse. After Nas showed Nia text messages proving Soulja Boy was cheating, the two women got into an argument. When Nia called Nas a "h-" the rapper jumped up and hit Nia in the face. Several security guards rushed forward to try and break up the fight. Soulja Boy tried to apologize to Nia by giving her a gold chain he was wearing.

Also during the episode, Ray J and Princess got into an argument over Princess' friendship with Ray J's ex-girlfriend Teairra Mari. Princess was also upset because she found out the "One Wish" singer was still in communication with Teairra. In the end, Princess tossed a drink in Ray J's face and broke up with him.

Another "Love & Hip Hop: Hollywood" couple going through a rough patch was Miles and Milan. The two men got into a fight because Miles won't tell Amber, his ex-girlfriend, he's gay. Earlier in the episode, Amber told Miles over lunch that she still wanted them to get back together. Miles attempted to tell her about his relationship with Milan but got cold feet. It's teased in next week's episode that Amber will finally learn the truth about her ex.

The final couple trying to work through issues was Willie Taylor and his wife Shanda Denyce. Willie, a former member of the boy band Day26, and Shanda recently moved to Los Angeles so Willie could launch his solo music career. However, things weren’t moving as fast as they hoped and the couple was running low on money. Shanda suggested she go back to exotic dancing as a way to make ends meet, but Willie got annoyed and told her he didn’t want her dancing anymore.
