Singer MICHAEL BUBLE has played down rumours he is set to marry his actress girlfriend EMILY BLUNT. Buble says he and The Devil Wears Prada star laughed at recent news reports suggesting the pair were engaged. He says, "We had a good laugh about that one." The Call Me Irresponsible hitmaker also claims he hates "gushing" celebrities who constantly showcase their relationships - and won't be calling Blunt pet names in the press. He says, "I get really turned off reading celebrities gushing about each other. 'She's my snooky-wooky-pooky and I'm the luckiest man in the world!'"
