Natalie Portman has dismissed reports linking her to Australian actor Chris Hemsworth. Rumors of dating started off after the two stars began filming for their forthcoming movie adaptation of the Thor comic book.

"Sparks have been flying since their first meeting. He seems to have a crush on her, and she clearly loves the attention," News.com.au quoted a source as telling Star. However, Portman's spokesperson told GossipCop: "This is not true."
