The comedian has apparently voiced his concerns that the Spice Girl will 'kick off' at him following his treatment of Geri Halliwell.
The Daily Star reports that a source close to Brand is avoiding places he is likely to bump into the singer turned designer.
The source said: "Russell's avoiding Posh at all costs. He's scared to visit the places where he used to bump into her."
"It's got so bad he's even changed his regular coffee shop because she goes there, and now goes to one that's two miles from his home in west Hollywood."
Changing coffee shops eh? It must be serious.

The source added: "He knows he didn't treat Geri too kindly, and is convinced Victoria will kick off when she sees him."
And we thought Victoria was Posh not Scary spice!
Russell and Geri had a whirlwind romance at the end of last month after the two bonded during the Olympics closing ceremony.
However, the relationship came to an end after the actor was spotted checking into a hotel with a mystery woman just thirteen days after it had started.
