Natalie Portman and 'Thor' Castmate Chris Hemsworth Dating!

23 December 2009

Another hot hook-up for the Hemsworth family, with Chris Hemsworth reportedly hooking up with Natalie Portman, while his brother Liam is romancing Miley Cyrus.

The pair met when they were both cast in the upcoming movie 'Thor' and have already started dating, despite the fact that shooting doesn't start until next month.

A source tells Star magazine, "Sparks have been flying since their first meeting. He seems to have a crush on her, and she clearly loves the attention."

Let's hope they don't break up before filming starts....AWKWARD MUCH?!

Natalie Portman's previous conquests include folk musician Devendra Banhart, who she met after starring in his music video 'Carmensita'.
