This, coming from a guy who named his kids Peaches, Pixie and Fifi Trixibelle!
Peaches Geldof and her fiancé Thomas Cohen welcomed their first son Astala Dylan Willow Geldof-Cohen two weeks ago.
Grandfather Bob admitted during an interview on UK TV that he hasn't even figured out how to pronounce the little boy's name, and he wishes he was called Leonard instead.
When the interviewer tried to pronounce "Astala", the muso laughed, "Shut up, I don't know. I don't know, I haven't said it yet I can't bring myself to say it."
He added, "I wanted to call him Leonard Leonard Cohen. 'Have you met my grandson Leonard Cohen?'"
Bob might not like Astala's name, but he loves everything else about him.
"He's a fantastic little chap. He is cute and they're really good parents so it's great. They're really happy," he said.
