Ariana Grande & Big Sean 'Heartbreak Disappointment' Amid Cheating Scandal: 'Bang Bang' Beauty Still 'Too Young,' Craves More Dating Freedom?

Despite seedy rumors currently surrounding their relationship, Ariana Grande and Big Sean make an adorable (and seemingly happy) young Hollywood couple. But is the 21-year-old "Break Free" beauty still a bit too young for the 26-year-old "Clique" rapper?

UPDATE: Ariana Grande & Big Sean Break-Up Drama: Nathan Sykes Dedicates New 'Emotional' Song To Ex-Girlfriend Amid 'Young Dating Freedom' Hype

As MstarsNews previously reported, Sean recently found himself in "hot water" after flirting with a groupie on Instagram (allegedly). Check it out:

Did the first major Hollywood break-up of 2015 already happen!?

According to the infamous gossip webloid MediaTakeOut.com, Nickelodeon's stunning pop princess probably doesn't consider her "I Don't F*ck With You" beau the "greatest guy" anymore...

The "Bang Bang" songstress allegedly caught her "Right There" boyfriend "creeping" with a popular online model. The report does not include the name of this supposed cyber mistress.

But once Grande figured out that the Hall Of Fame superstar was talking to another girl behind her back, she totally freaked. An alleged MTO "snitch" insists that Sean never actually cheated - he just flirted with the Instagram hottie through text message. Still, the duo planned on "hooking up" on his next trip to Miami... and maybe now that will actually happen since he's rumoredly single again!

"[Big Sean] never slept with her, but she was down - when he came to Miami next," the insider reveals.

So, how did the former "Sam and Cat" sweetheart catch her boyfriend creeping around? Well, sexting can get you in some major trouble!

"Ariana got into his phone somehow, and saw all the messages," the source (allegedly close to this unidentified hottie) explains. "Ariana actually called and started talking sh*t. It was kind of funny to us."

Sean later denied the cheating buzz on Twitter:

@BigSean: "Lotta ups and downs during this holiday... But I appreciate all the love n support. I'm thankful to have fam, friends n everything good! I'm thankful for all of u."

@BigSean: "No point in worrying bout things you can't control... Boss up in 2015! No sucka sh*t allowed."

@BigSean: "Don't get distracted on the Internet, focus on what's at hand!"

So apparently the rumors were over-exaggerated, and the couple never broke-up. But are things still getting a bit too serious for Grande, who maybe wants to take advantage of the "young single" life for a bit before settling down?

An alleged Dish Nation "snitch" reveals this lengthy insider's scoop:

"Ariana told their friends she's not even thinking of marriage yet. She's very happy in her relationship with Big Sean and loves him very dearly. They are soul mates and do everything together... But she's still so young. She said to her friends that's there's still much more for her to see in the world. She wants to go traveling, not stop in countries for one night for tours, but properly explore like any young person wants to do... She still feels like she has to live a little-and doesn't want to be tied down in a marriage, have kids, or do anything like that for a while. Obviously, that left Big Sean a little upset-and he's just wondering if Ariana feels the same as he does... He's [smitten] with her, they grew up with each other and their relationship is built upon a deep affection for one another... He just would like to know if they're on the same page, and if perhaps wedding bells are in their future."

So, is Sean actually the one left with a broken heart? Or will the duo go-with-the-flow and eventally work things out? Leave your thoughts in the comments section below, MstarsNews fans!
