Rihanna & Gwen Stefani Beef: Blake Shelton Supports Hot 'The Voice' Rival, Not New Girlfriend?

Rumors suggest that Blake Shelton's now romancing Gwen Stefani, but apparently the No Doubt beauty isn't his only "The Voice" crush!

Just last month, the "Sangria" crooner gushed over Season 9 mentor Rihanna in an exclusive HollywoodLife.com interview:

"Rihanna is hot... She was so great, so funny, [and] so honest - she was really good at that. She really took it seriously and was very good at the job!"

Unfortunately they haven't hung-out since RiRi's brief appearance on the show, but that didn't stop Shelton from praising her even more on Monday morning's episode of "Live! with Kelly and Michael" (November 16).

The 39-year-old country superstar talked about his awesome experience working alongside the "FourFiveSeconds" songstress, and he still (jokingly) hopes "Blianna" might become a thing.

But what about Shelton's new love interest that he did actually meet while filming? Apparently his relationship with Gavin Rossdale's ex-wife continues growing strong, but he didn't mention Stefani's name once during the casual morning discussion. Maybe he's not ready for such intense chemistry, especially after seedy online gossip insinuated earlier this month that the 46-year-old "Hella Good" rocker was already pregnant with his first child...

Of course Miranda Lambert's former hubby blasted those crazy "baby bump" rumors very fast.

Perhaps he's just keeping quiet so that they can enjoy their blossoming relationship without any extra drama (especially concerning the media)?

Well, Stefani's supposedly "jealous" of the 27-year-old Barbadian pop sensation already, so hopefully this doesn't cause any more unnecessary issues. As MstarsNews reported over the summer:

The "Bubble Pop Electric" superstar still holds a major grudge against RiRi that started way back in 2011. At the time, Stefani insisted that she was different from the Anti BadGal 'because I usually put pants on.' The "BBHMM" singer never actually responded, but according to an alleged National Inquirer insider:

"Rihanna's the type to hold a grudge and thought Gwen was way out of line."

So what will happen once the ladies finally ready to face-off (on camera)?

"Gwen's convinced Rihanna's being paid way too much and that she'll throw herself around on the show and expect to be queen bee," the snitch reveals. "[She's] not going to sit back and let that happen."
