Megan Fox failed to dampen rumours she's dating her Transformers co-star Shia LaBeouf as she took the actor to an early morning physical therapy session.

The pair were spotted leaving the actor's house in Los Angeles yesterday shortly after 8am and visited a doughnut shop before they continued to the clinic.

LaBeouf, who is receiving treatment for a hand injury, has been repeatedly linked to Fox during the promotional tour for the Transformers sequel, which ended with the London premiere last week.

The actor is reported to have said at the red carpet event in Leicester Square that he would “maybe” considering dating Fox now that she was single.

The actress, who has admitted to being a bisexual, has been linked to number of Hollywood stars since the demise of her relationship with ex-fiancée Brian Austin Green.

She told Stuff recently that she was “nervous” about being single, adding: "It's very scary. I'm now looking for a guy who's really honest and funny."
