The Daily Telegraph reports

Jessica Mauboy can't put a foot wrong. The Aussie pop singer's second movie The Sapphires has put her on the radar in LA and now she's scored a plum gig at one of Britain's celeb weddings of the year.

And earlier this week she was spotted hanging out at Simon Cowell's house in Beverly Hills.

Mauboy's The Sapphires co-star Chris O'Dowd - the Irish funnyman and unlikely sex symbol from Bridesmaids and The IT Crowd - is making good use of his connection to the singer, especially in relation to his wedding late next month to UK TV presenter Dawn Porter.

"I'm very excited about the wedding and very excited about The Sapphires involvement in it - we're going to have the lovely Jess sing at the ceremony," O'Dowd said.

O'Dowd has joked that Porter, former co-host of stylist Gok Wan's series How to Look Good Naked, "chased me around the world". Mauboy yesterday said Hollywood had already been calling - even before The Sapphires opens locally on August 9.

"We're in a lot of auditions now. It's a great place to be. I love to be on a buzz, on a roll," Mauboy said.

"It's not top secret it ... oh, it kind of is!

"We're waiting for call-backs. And amongst all that, trying to push my music at the same time."
