Honestly, these unlikely celebrity couples are like buses. You wait aaaages for one and then two come along at once. Tsssk. Typical.
Hot on the heels of Marc Anthony and Chloe Green going public with their romance (we've only just picked our jaws up off the floor about that one) Natalie Imbruglia has been linked to fellow Aussie Russell Crowe.
A source said: "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."
Russell is currently in the midst of £15 million divorce from his wife Danielle Spencer.
The couple split in October last year after nine years of marriage.
Natalie was most recently linked to One Direction star Harry Styles when they were spotted enjoying each other's company at James Corden's wedding.
However, Harry played down the reports during a recent appearance on 'Alan Carr: Chatty Man'.
"We were at a wedding, James Corden's wedding," he said. "We'd never met before, and that was literally it. We had a drink," he said.
"I guess we kinda left at the same time so it might have looked a bit dodgy."

Brad Pitt and Sinitta
Yep, Brad Pitt really did step out with Simon Cowell's shadow. Well, not his real shadow, but the next best thing - Sinitta. The pair dated from 1987-89. (Pic: Rex)
Angelina Jolie and Billy Bob Thornton
It's hard to think of Ange pre-Pitt, but her union with Billy Bob was actually her second marriage. Angelina wed the <em>Armageddon</em> star who was 20 years her senior in 2000, only to divorce three years later. (Pic: PA)
Vanessa Feltz and Ben Ofoedu
After a failed marriage and years of life as a singleton, Vanessa hooked up with Phats and Small singer Ben Ofoedu. If that doesn't mean anything to you, perhaps this will - "Hey what's wrong with you? You're looking kind of down to me". (Pic: WENN)
Billie Piper and Chris Evans
When 18-year-old Billie tied the knot with DJ Chris Evans during a trip to Las Vegas in 2000, many said it wouldn't last. And, well, it didn't. However, despite ending their relationship three years later, the pair still remain great friends and they even attended each other's weddings to their current partners. (Pic: PA)
Cher and Tom Cruise
A few years ago, Cher revealed to the world she shared a romance with Tom during the 80s, describing him as "just the most adorable man you can imagine". (Pic: WENN)
George Clooney and Lisa Snowdon
Lisa Snowdon went from little-known model to Mrs George Clooney when she began dating the actor in 2000. They enjoyed an on-off five year romance, before finally calling off their love affair in 2005. (Pic: PA)

Kate Hudson and Matt Belamy l

Charlie Brooker and Konnie Huq
<em>Blue Peter </em>host and <em>Xtra Factor</em> flop Konnie should be the epitome of everything TV grump Charlie criticises, but somehow the pair managed to make it work enough for them to wed last year. They're currently expecting their first child. (Pic: PA)
Lembit Opik and Gabriela Irimia
You really couldn't make this kind of pairing up. MP Lembit obviously wasn't shy in touching Gabriela's bum as he nabbed the Cheeky Girl in 2005, after ditching TV weather girl Sian Lloyd. (Pic: PA)
Mel B and Eddie Murphy
When the Spice Girls hung up their platform shoes, Mel headed stateside where she hooked up with the <em>Nutty Professor</em> star. When Mel claimed she was mothering Eddie's child in 2007, after the pair had broken up, Eddie ordered a paternity test, only to find he was the father of Angel Iris after all. (Pic: WENN)
Catherine Tate and Jason Orange
The Take That singer was rumoured to be dating the comedienne after they were spotted on a series of dates in 2011. However, the couple are recently said to have gone their separate ways. (Pic: Getty / PA)
