It’s all over for this reality couple after ANOTHER cheating scandal!

It's been a rocky few weeks for Made In Chelsea couple Tiffany Watson and Sam Thompson, but things really came to a head in last night's episode of the show.

The drama started for the couple last month when Sam admitted he had shared a bed with his MIC co-star Fran Newman-Young after a party, although he insisted nothing happened. Tiffany, who joined the show at the beginning of this series, finally agreed to take him back, but last night another scandal emerged.

Tiffany's friend Binky was the one to break the news that Sam had cheated again, and that this time there was proof. "At your birthday I think you guys went your separate ways… Lonan told me he 100% saw Sam with another girl. Full on kissing," she told a devastated Tiffany.

Sam initially claimed the whole thing was a lie, but he later changed his story and admitted to pal Josh Shepherd that he had indeed kissed someone else. 

The cheating was made all the more painful for Tiffany by the fact that her and Sam had recently begun to discuss plans for the future. "The other day he was like 'I can see us being together for years'. Why say that then do this?" she told a friend.

Despite love rat Sam's pleas for a second (well, third) chance, Tiffany unceremoniously dumped him at the end of the episode.

"I don’t want to hear you’re sorry," she told him. "You're only upset because you got caught. I'm glad it happened now because now I know what type of person you are and I don't have to associate with people like you."

Sam took to Twitter to express his regret, but we reckon it's too little too late:

Hopefully Tiffany sticks to her guns!
