Rihanna vs. Serena Williams, Drake hoping for sexy threesome? Twitter fans respond to rumored 'girl fight' and rapper's 'baller' status

Rumors suggest that during Drake's concert in Paris on Monday evening (Feb. 24), Rihanna and Serena Williams got into a little "tiff" backstage.

And here's why.

As Mstars previously reported:

According to the infamous gossip webloid MediaTakeOut.com, "things went down" backstage at Drizzy's concert when popular tennis starlet Serena Williams vehemently "confronted" the "Diamonds" songstress.

A "rock-solid" snitch tells MTO that Drake invited BOTH RiRi and Williams to the show. Apparently, the Young Money rapper continues hooking-up with the two ladies - at the same time! Well, he allegedly promised both beauties that he'd spend some one-on-one time with them after the performance. That didn't happen...

Once Williams discovered that RiRi was also backstage at the show, she got right up in her face. Some not-so-nice words were exchanged, but nothing physical or violent occurred. The Barbadian beauty's security were right on-hand in case things got out-of-control.

Anyway, Drizzy DID take one of the girls out after the concert... and it wasn't Williams. The Nothing Was the Same crooner grabbed a romantic dinner with Chris Brown's ex, and then they went to party at the popular nightclub Club 79. The former Olympic gold medalist wasn't even invited.

So what's up with that?

Funny thing is, Williams is rumoredly dating her tennis coach Patrick Mouratoglou. But leading up to this "beef" with RiRi on Monday, Williams tweeted:

@serenawilliams: "Everybody needs love."

Interesting... Meanwhile, rumors continuously suggest that although they're not dating, Drizzy and Rihanna are definitely "hooking-up."

Both starlets have yet to respond to the "girl fight" gossip on Twitter, but Williams did recently tweet:

@serenawilliams: "Me. Mine. Alone. Myself. I. One. Solo. Unaccompanied."

Sort of ominous... is she jealous that Drizzy ultimately chose to spend the nigth with RiRi?

Wonder if Drake was hoping for a sexy ménage à trois... sounds like something the crazy Barbadian beauty might be down for!

Here's what some Twitter fans are saying about the rumored Rihanna and Serena Williams beef. Oh, and Drizzy's "baller" status:

@CoolAzz_Ney: "So Rihanna AND Serena Williams both f*cking with drake? Haha."

@beealeks_ : "Rihanna and Serenea Williams were about to fight... that's a joke, Rihanna would have definitely died that night."

@Jon_Tennis: "Woow! :o Serena vs. Rihanna. No wonder Drake couldn't choose."

@KingBLuvsMe: "at K104 saying Serena Williams will hit Rihanna harder than Chris Brown did cause she's with Drake."

@DaveyDooks: "YOOO DRAKE IS A BALLER!! FWBs WITH BOTH RIHANNA AND SERENA WILLIAMS! #DRIZZY #CHAMPAGNEPAPI."

Do Mstars readers believe all the "secret hook-ups" hype?
