The pair began dating in 2010 and became engaged the following year, but they called off the wedding in April, despite continuing their relationship.
However, it was revealed in July that they had parted ways, and George admits he's still single and wants to take his time getting over Keegan.
He told Britain's Fabulous magazine: "I'm not dating or anything. I'm just single and getting on with work and the new record, so I'm very busy indeed.
"I've not long been single, so it takes time to move on from someone who you really... well, especially someone like Michelle, anyway. I'm not ready for anything with anyone else.
"She'll always be special to me. She's a nice girl, a great girl, so I just wish her all the best. You'll never hear me say a bad word about her."
