Shia Labeouf has reunited with on-and-off girlfriend Mia Goth, six months after confessing he "would have killed" her following a raging bust-up in Germany.

The 'Transformers' star split from Goth last summer after he was caught on camera verbally chastising the actress on the street, prompting a group of male strangers break up the fight.

Labeouf, 29, was subsequently linked to another actress Sasha Lane, after walking hand-in-hand with her in California in August, but it appears he gone back to his ex.

The former couple was photographed openly kissing in the middle of a crosswalk after a date in Los Angeles on January 6, when Shia made no effort to hide his affection for his Nymphomaniac: Vol II co-star.
