Ariana Grande Disses Big Sean, Dating Nathan Sykes After 'Selfish' Break-Up? Ex-Boyfriend 'Obsessed' Amid New Nariana Collaboration Buzz

Rapper Big Sean did not simply break things off with (ex) girlfriend Ariana Grande because of her younger age. Apparently, the "Break Free" songstress was also very "selfish" and "immature." But maybe some guys actually find such diva-esque behavior attractive - including Nathan Sykes?

Grande and her former The Wanted beau are NOT getting back together. Sykes insists that despite their failed romance, the two pop sensations still remain very close friends. But according to an alleged insider for the popular gossip webloid HollywoodLife.com, the 21-year-old beauty and Sykes rarely talk anymore!

"We're all really confused as to why Nathan keeps saying that he and Ariana talk so much," the snitch reveals. "They don't talk to each other at all."

But that doesn't mean any hard feelings currently exist between the "Almost Is Never Enough" collaborators. Still, fans shouldn't expect a Nariana reunion anytime soon! However, the exes DID ultimately agree on a song "swap," so Grande may be featured on one of Sykes' new solo tracks soon!

As MstarsNews previously reported, the "I Don't F*ck With You" emcee dumped the 21-year-old Nickelodeon princess because she didn't fully support (or even acknoweldge) his career:

Sean was supposedly ready to kick Grande to the curb back in February when she ditched his highly-anticipated House of Blues performance in West Hollywood. Several big-name celebrity pals (includingKanye West, Kendall/Kylie Jenner, and Tyga) showed-up, but the "Bang Bang" beauty was allegedly "too busy" preparing for the Grammys to support her man (via TMZ).

They official broke-up in April. Now, Grande is searching for a new "Scream Queens" lover while the Detroit native supposedly leans on "Glee" starlet Naya Rivera for support.

Apparently, the split was rather bitter. Will the "Blessings" superstar ever forgive Grande if she grows-up a bit? Or should she give Sykes another chance? Sound-off in the comments section below!
