Josh Hartnett is Dating Singer Nadine Coyle

˝They were spotted at Blanco 101 looking very much like a couple and chatting over drinks until the early hours.˝

Josh Hartnett is reportedly dating Girls Aloud singer Nadine Coyle. The pair have sparked romance rumours after being seen together on a number occasions in Los Angeles last week, including drinks at temporary Oscar venue Blanco 101.

A source told Britain's Daily Star newspaper: "The whole of Hollywood was talking about Josh and this pretty Irish girl. "Not everyone knows Girls Aloud here so people were trying to work out who this stunning girl was. "They were spotted at Blanco 101 looking very much like a couple and chatting over drinks until the early hours."

Nadine - whose on/off relationship with 'Desperate Housewives' hunk Jesse Metcalfe' ended in January - was supposed to be flying back to the UK for the BRIT Awards earlier this month, but was forced to remain in the US when she lost her passport.Sources say the 22-year-old singer quickly got over her disappointment thanks to her new friend Josh.

Meanwhile, the 29-year-old actor - who previously dated Scarlett Johansson and has been romantically linked to Rihanna, Kirsten Dunst and Rumer Willis - was left red-faced when he was forced to fly in economy class back to New York following the Oscars.

A source said: "The flight was so overbooked there was no way he was going to get upgraded, but that didn't stop him trying. There were so many stars on the flight, when he went up to the counter to ask about a waiting list they told him, 'You're number 55.' "
