Transformers actress Isabel Lucas has shut down reports she was dating Liam Hemsworth, insisting she’s just ‘good friends’ with the actor and his family.

Thor actor Liam was said to have ‘sought comfort’ in Isabel, 34, following his split from wife Miley Cyrus in August after seven months of marriage.

In a bizarre twist, it turns out Isabel actually dated Liam’s older brother Chris Hemsworth for three years between 2005 and 2008 after meeting on the set of Home and Away.

However, the actress says there’s nothing to the rumours but she was pretty entertained reading them all the while knowing the truth.

Clearing up the speculation in an interview with Australia’s the Daily Telegraph, Isabel said: ‘Yeah, reading that was fun. Obviously we are just good friends.’

It seems she’s still on good terms with Chris too as she added: ‘The Hemsworths are a beautiful family. It is a strong community in Byron and I am so grateful to have so many beautiful friends there.’

In addition to her role in Home and Away, Isabel has gone on to star in Transformers: Revenge of the Fallen, MacGyver, Immortals and Red Dawn, the latter of which saw her co-star with Chris again. Isabel also had a starring role in Ed Sheeran’s 2012 music video for Give Me Love.

In August, a source told Woman’s Day of Isabel and Liam: ‘Liam’s in Byron staying with Chris. Isabel moves in the same social circles up there, and they’ve spent some time together.

‘They’ve become quite good friends. She’s there to take his mind off things, and she’s been an excellent person to turn to for advice.’

They added: ‘She’s in Europe at the moment and feels bad she’s jetted out during the worst of it for Liam, but even so, she’s been keeping in touch via text.’

Following his shock split from Miley, Liam was most recently thought to have been dating Dynasty actress Maddison Brown after they were spotted enjoying PDA on a date.

An insider told HollywoodLife at the time of their romantic dinner date: ‘He appeared to be a gentleman throughout. They were holding hands and he held her close while opening doors for her when they stepped outside to get to their table. They were in zero rush and were there for over an hour.

‘He requested a table outside to enjoy the weather. No one recognised him or most of the other patrons played dumb because they weren’t bugging him or them at all.’

Meanwhile, Miley struck up a romance with Kaitlynn Carter just a day after their marriage split was announced, but is now dating Cody Simpson.
