Beyonce vs. Kim Kardashian vs. Rihanna: cheating scandals erupt after Jay-Z & Solange elevator attack, which hip-hop couple will survive? [POLL]

Despite ongoing "cheating" rumors, hip-hop's top power couples seem to be doing very well. Jay-Z and Beyonce are all smiles, Kim Kardashian and Kanye West are "happy in love," and Rihanna and Drake are "infatuated" with one another. But in the end, which Hollywood relationship will ultimately survive?

Solange Knowles' epic elevator showdown with HOV continues going viral online. Several fans believe that it has something to do with the Magna Carta rapper having a hot-and-steamy affair behind his wife's back. Read more on the whole violent ordeal here:

Meanwhile, KimYe continue bonding over their affection for baby North West. The soon-to-be-newlyweds just celebrated an amazing Mother's Day together:

kimkardashian: "This little girl has changed my world in more ways than I ever could have imagined! Being a mom is the most rewarding feeling in the world! Happy Mothers Day to all of the moms out there!"

BUT - does Yeezy have a "thing" for his young music protege, Pia Mia Perez? Hmm...

Sounds crazy, but that's what some insiders are suggesting!

As for Drizzy and RiRi... their relationship's still "fresh." They make an adorable pair, but the truth is, they're still both so young, wild, and free!

And VERY busy with their own separate careers. Drake's openly flirtatious personality doesn't help things, either. Gossip has it that he might be fooling around behind RiRi's back, and she's had enough.

Some fans find a break-up inevitable, but will they make it in the long-run?

So, Mstars readers, which is your favorite hip-hop power couple?
