Few fans can remember a time when Chris Hemsworth wasn't happily married to Elsa Pataky. After all, they met more than a decade ago, have been married almost as long, and have three adorable children together.

Throughout his brother Liam's marriage to Miley Cyrus, Chris and his wife served as the picture-perfect comparison to what turned out to be a trainwreck. Especially when Miley went a little off the rails after their breakup, Elsa even spoke up about Liam deserving better.

But before Chris got married to Elsa, he dated someone else -- even though the headlines were far fewer at that time. It may seem like forever ago, but Chris Hemsworth once dated Isabel Lucas. So who is she, and why did they break up?

Who Is Chris Hemsworth's Ex-Girlfriend Isabel Lucas?

Isabel Lucas is more than just "Chris Hemsworth's ex." She's an actress, model, and celebrity in her own right. Also hailing from Australia, Lucas has an extensive resume in Hollywood, appearing in various TV series and movies, starting with a role in 'Transformers: Revenge of the Fallen.'

She even appeared in Ed Sheeran's music video for 'Give Me Love.' More recently, she appeared on 'MacGyver,' and she has a couple of movies in progress at the moment.

But before that, Isabel was on the TV series 'Home and Away,' where she worked with Chris Hemsworth. Clearly, that's how the pair met -- but their relationship ended after about three years, in 2008.

Lucas went on to date Adrien Grenier, Jared Leto, and singer Angus Stone.

Why Did Chris Hemsworth Break Up With Isabel Lucas?

Though their breakup did make headlines, it seems there is no bad blood between Isabel Lucas and Chris Hemsworth. Their relationship also doesn't seem to have overlapped with Chris' meeting and wooing Elsa Pataky.

So, fans can assume everything is cool between the exes, especially since Isabel splits her time between Los Angeles and the same city where Chris and Elsa live. Chris and Liam have even run into Isabel in Byron Bay, and paparazzi photographs suggest that the exes can easily chat without it being awkward. No word on what Elsa thinks of that, though.

And while tabloids suggested that Isabel and Liam were dating after he split from Miley, both parties noted they were just friends.

It seems that all is well that ends well, though. Not only are fans obsessed with what seems to be a great marriage between Chris and Elsa, but Pataky is also the perfect female Thor, they note.

Although some gossip sites have tried to link Chris with Isabel these days, it doesn't seem there's any truth to trouble in that Hemsworth marriage.
