New Couple Klaxon! Are Natalie Imbruglia And Russell Crowe Sweethearts?

As one showmance ends (we're still weeping over the Michelle Williams/Jason Segel split) another starts to bloom. The latest slab love match? Les Miserables actor Russell Crowe and Nineties pop star Natalie Imbruglia.

The Aussie pair were spotted at the AACTA Awards in LA getting up close and personal, prompting rumours they're an item, and now they've added fuel to the fire as they got flirty after the Oscars.

A source allegedly told The Mirror, "They were all over one another and doing little to hide their flirting. They were being really playful and jokey with one another. You could see they really hit it off.

"They then went back to Russell's room with some friends where they were partying until broad daylight. They were singing really loudly together around the piano, belting out some show tunes, and they looked pretty cosy when everyone left them to it."

The sign of true love? Singing show tunes together - you heard it hear first.

While Natalie has been linked to a string of men, including Lenny Kravitz, Prince Harry and even Harry Styles, this potential new hook up comes as Russ gets ready for a £15million(!) divorce from his wife of nine years, Danielle Spencer - yeesh.

Speaking of divorce...
