Ariana Grande and boyfriend Big Sean have reportedly split due to jealousy but a rep for the "Bang Bang" singer quickly nixed the rumors.

"A rep for Ariana told Mail Online that the reports have no basis and are 'absolutely' false," the publication said.

However, Ariana Grande and boyfriend Big Sean didn't spend Christmas together as they were with their respective families. The rapper's grandmother passed away on December 23, which he confirmed on his social media: "My grandma passed away a couple days ago. I haven't said anything to anyone because honestly I feel like she's still here."

According to Hollywood Life, the couple's relationship is hounded by jealousy. However, they are still together, just "not as strong as they once were."

"Sean has also told buddies that they're having some issues. They have some issues and might break up because of them but they are still a couple," the website said.

Worse, Ariana Grande reportedly found some photos on Big Sean's phone that suggested he wasn't loyal, said The Star.

"She refuses to return his calls. She feels completely violated and has lost all trust in him," it said.

On Christmas Eve, Ariana Grande went home to her family to spend the holidays. She posted a photo of her grandmother and dogs on her social media, which she captioned: "Surprised nonna w/ a new friend & tiny companion... she named her noel."

Ariana Grande also paid tribute to her fans on New Year's Day with a tweet: "Hope i'm not too late to say this but just wanna thank you 1 more time from the bottom of my heart for making 2014 so special!! a dream. ily."

She added: "Even tho there were some difficult moments i'm very appreciative of the love u continuously show. u make everything better :) really love u."

Ariana Grande, however, did not address the breakup rumors with Big Sean in her holidays posts.
