LIAM HEMSWORTH has traded one ticking time bomb for another!

After dumping out-of-control fiancee Miley Cyrus, the “Hunger Games” hunk quickly hooked up with troubled Mexican soap star and singer Eiza Gonzalez.

The 23-year-old beauty was reportedly hospitalized for problems arising from eating disorders earlier this year – and she’s also struggled with attention deficit disorder.

“Liam has no idea what he’s getting into with Eiza,” an insider told The ENQUIRER. “She’s a sweet girl, but she’s got all sorts of issues. In late June, the Mexican media ran stories that she was under the care of doctors for several days after a bout with bulimia that left her unconscious.

“Eiza has denied having an eating disorder, but this wasn’t the first time reports surfaced.”

Eiza reportedly did admit to ER docs that she vomits regularly – and when she left the hospital, she reportedly was advised to get rehab for potentially serious eating problems.

Ironically, on Latin TV Eiza played a character who led a secret life as a rocker – just like Miley’s “Hannah Montana.”

Now she has something else else in common with Miley, 20 – Liam. She first met the 23-year-old Australian on Sept. 14 at the Las Vegas XS nightclub. Two days later, they were spotted leaving a house in Los Angeles together. And the following day a photo showed the two smooch­ing outside her apartment.

In light of Liam’s problems with wild-child Miley, the source says: “Eiza is the wrong kind of girl for Liam to get involved with now. He needs to give it a rest.”
