The Daily Star reports that the new boyfriend of Girls Aloud star Sarah Harding has issued a warning to her previous guy, Mikey Green of Phixx.

When Calum Best was introduced to Mikey a few weeks ago, he told the singer, “Good to meet you but trust me mate, it’s the first time and the last. I won’t be seeing you ever again.”

A pal of Calum’s revealed that, “He feels threatened by Mikey because of how long he and Sarah were together. However, he is not prepared to tolerate any kind of relationship between them.”

But despite the heavy hint, it appears that Mikey is not prepared to back off that easily and has declared, “We’re friends, we see each other every now and again and we are texting all the time. So who knows what will happen?”
