Rihanna vs. Lolo Jones Twitter beef: Olympic beauty disses rapper Drake's girlfriend, will Chris Brown's ex respond?

There's Team Rihanna. Then there are the RiRi haters.

And apparently, Olympic track and field/bobsled starlet Lolo Jones is one of those "fans" who enjoys bashing the "Diamonds" songstress.

On Thursday (April 10), Jones tweeted:

@lolojones: "It's amazing that Drake is hosting the @Espys but it's gonna be tough for him to hand out all those awards to Rihanna's ex boyfriends."

Ouch - what does RiRi's love life really have to do with anything?

Of course, several of Rihanna's diehard fans quickly came to her defense. And Jones' response?

@lolojones: "paleeeze. watching monologues of past espys, my joke was PG compared to how The ESPY Host will roast athletes there..."

Jones stopped her Twitter-bashing there, later posting:

@lolojones: "My first Winter Olympic ring now joins my two Summer rings. Being a part of Women's USA Bobsled was a life changer."

Surprisingly, Chris Brown's ex has yet to respond. Rihanna's latest tweet:

Apparently she has other "more important" things on the mind. But do Mstars readers see a major Twitter feud brewing?
