Big Sean 'believes Ariana Grande's on-stage embrace with Justin Bieber was a calculated move to hurt him following their split'

They split up at the start of the month after just eight months of dating, reportedly due to conflicting schedules.

But Big Sean, 27, is said to feel that 21-year-old Ariana Grande's recent performance, in which Justin Bieber joined her on-stage in LA and hugged her from behind was a calculated move to hurt him.

Sources close to the former couple told TMZ: 'Sean claims it was him who broke off the relationship because she was "immature".'

The site adds that their relationship went downhill in February, when she failed to support him at his star-studded House Of Blues appearance in West Hollywood.

Kanye West, Justin Bieber, Jennifer Lopez, Chris Brown and Jay Z were just some of the high-profile names who attended - but Ariana was absent. 

TMZ write: 'We're told she needed to get ready for the Grammys the next day, which he found selfish and he travelled ten times more than she did to see her.

Adding: 'He claimed once she demanded that he blow tens of thousands of dollars to take a private jet to see her. Sean, who grew up poor, felt she was a spendthrift ... a sign of immaturity.'

MailOnline has contacted a spokesperson for Ariana Grande and Big Sean for comment.  

Meanwhile, on Tuesday the songbird went to Twitter to tell her followers she was just fine: 

She wrote: 'I love u babes so much. you're a bunch of angels honestly. your love / care is appreciated so much. i'm good i promise.'

Turns out the two were just too busy, a source told UsWeekly

'They made the decision to part ways because their conflicting touring schedules would keep them apart over the next year,' the insider said.

Currently the rapper is on tour in the US as the beauty is getting set to start the second leg of her Honeymoon Tour in Paris in May.

'They both deeply care for each other and remain close friends,' their reps said in a joint statement.

Big Sean has yet to talk about the break up, but he did look happy when he sang One Man Can Change the World on The Tonight Show with Jimmy Fallon on Monday. 

They seemed to be fine just a few weeks ago.

On April 4, Big Sean tweeted: 'Just know I love u and I care for ya.'

'Love u babes the most. you just can't imagine,' the Victorious actress tweeted, seeming to be echoing the Control hitmaker's sentiments. 

Earlier this month, Justin Bieber surprised Ariana's fans by joining her on stage during her tour stop in Inglewood, California.

The star got rather intimate with the songstress, which followed with Big Sean tweeting: 'This kid is about to learn not to touch my girl like that. Beliebe that.'

Yet, sources told TMZ that the tweet was a fake and that the rapper was never mad at the Baby singer.

Now, insiders insist that Big Sean and Ariana's split has nothing to do with the Biebs, reports TMZ.
