Rihanna Boob Job, Leonardo DiCaprio Turned-On? Flaunts 'Enhanced' Cleavage At iHeartRadio Music Awards, Twitter Approves [PHOTOS]

Rihanna performed her new hit single "B*tch Better Have My Money [BBHMM]" at the 2015 iHeartRadio Music Awards on Sunday evening (March 29). RiRi's killer vocals and wacky ensemble definitely stole the show - but several fans REALLY took notice of the songstress' "enhanced" cleavage!

Did the 27-year-old Barbadian beauty mysteriously go up a cup-size? Or perhaps her skin-tight black mini-dress did the boostful trick. Either way, loyal members of #TeamNavy are loving the new voluptuous look! #Boobs is now trending on Twitter:

@SelenaONAIR: "omg her boobs look soooo good!! #iHeartAwards @rihanna."

@ZARRlH: "Rihanna's boobs looked amazing in that dress."

@YerdMe_CMB: "All these pictures of Rihanna and I'm just staring at her boobs in all of them..."

@kanyespizza: "BOOBS BOOBS OMG BOOBS @rihanna ."

@katyshomie_: "Rihanna's boobs went from 0 to 100 real quick."

@irwhitestyles: "Rihanna's boobs are goals."

@_LordJah: "Rihanna has made and is making so much positive black history and yet all people can focus on is how she had her boobs out. Smfh."

@_LLexington: "It's hard to hate Rihanna. Her skin is always glowing. Her boobs sit perfectly and her hair is love. She's a cutie."

@yungtwizzler: "I'd love 2 use a lint roller on Rihanna's boobs. Like hire me. No pay is ok too. Let me be your slave. Punish me idc."

@RunHoodRun: "Dayum Rihanna your boobs doe :)."

And now rumors suggest that RiRi went "under the knife" to achieve this boobylicious look. Do MstarsNews readers believe the plastic surgery hype?

Surprisingly, the "Home" starlet did NOT experience an embarrassing wardrobe malfunction - too bad!

The "Pour It Up" singer is still supposedly dating infamous Hollywood bachelor, Leonardo DiCaprio. Maybe he's actually a fan of the bigger ta-tas?

Rihanna's highly-anticipated new album should hit airwaves sometime this year, although the official release date still remains unconfirmed.

The beloved #BadGal was not nominated for any awards at the second-annual event, but just wait until next year!
