The `Keeping Up With The Kardashians` star recently split from Rita Ora and launched a string of abusive messages thought to be aimed at her on Twitter but Rob now insists he is happier than he has been in a long time.

Speaking to Ryan Seacrest on Kiis FM, he said: "I`m very, very single. I`m very, very happy. For the first time in a long time, so it`s a good thing. Honestly, it`s all about working out in the new year and businesses. This is just the beginning."

While Rob, 25, claimed the messages - in which he claimed an ex girlfriend cheated on him with over 20 men while they were together - were not about Rita, he was left so upset by their split that he unfollowed Rita on Twitter and deleted photos of them together on photo-based social networking site Instagram.

A source said: "They`d only decided to go public with the romance a couple of months ago so as not to put any pressure on themselves but they`ve already split. Rob has now deleted everything on Twitter that reminds him of Rita."
