Scott Disick is desperate to get back together with his girlfriend Sofia Richie after she dumped him last week for allegedly cheating on her.

The 'Keeping Up With the Kardashians' star was shocked when the 19-year-old model called it quits and moved her possessions out of his home when photographs emerged of him all over another girl at Kanye West's 'Ye' listening party.

And, although at first he thought it was just a lovers' tiff, he's now panicking that she's serious about their split and has been blowing up her phone trying to apologise. 

A source told The Sun Online: "Scott was really shocked when Sofia split up with him, presumed it was just another row and that it would just take a little begging and cajoling to win her around again - but now he's panicking that it really is over.

"When Kourtney [Kardashian, his ex and mother of his three children] would break up with him, he'd be in the dog house for a week and they'd be back on. 

"He thought it would be the same with Sofia - that he could charm her and she'd forgive him. But so far, it's not working. He's been non stop calling her, sending her messages and begging her to meet him - so far she's just not interested. Everyone thinks he'll win her over - but she's taken her things and moved out of his house."

Sofia - who has been dating Scott for just over a year - was reportedly encouraged to leave him by her father Lionel Richie as he has insisted she "deserves better."

A source said recently: "Her dad got to her and was a major influence. He told her enough is enough and she deserves better than this ... She is upset and sad but feels like she had no choice and she couldn't stand for being cheated on and being in such a toxic relationship. She is relying on her family for support and they are trying to keep her busy. She is spending her time with them and with her close friends."

Scott - who is known for his womanising and wild partying - has three children; Mason, eight, Penelope, five, and Reign, three, with his former partner Kourtney.
