The 2008 British Eurovision entrant claimed the programme would be weaker without Osbourne on the judging panel.
"I'm not sure if I'll even bother watching it," Abraham told DS. "I like the fact that you never know what Sharon's going to be getting up to, or what water she is going to be throwing over Louis.
"For me, it's going to be a bit strange."
When asked what he thought about Dannii Minogue's performance on the reality show, he commented: "I find Dannii a bit bland. Sharon's got a bit more to her.
"[Sharon] has got so much more experience, she's been through the business and seen so many more high profile acts than I'm sure Dannii has."
He added: "I wish Dannii well, but for me, Sharon will always be the main person."
