Nothing to see here! Megan Fox is defending her former "Transformers" costar Shia LaBeouf following his recent arrested months of bizarre behavior. The actress had only nice things to say about her old pal while recently promoting her film "Teenage Mutant Ninja Turtles."

"I'm not worried about Shia. I love my Shia. He's perfectly fine," Fox, 28, told the New York Daily News. "I haven't talked to him in a couple of years, but I don't worry about him."

"He's a brilliant kid, talented and funny," the mom of two continued. "There's no reason to worry." (The former costars last played a couple onscreen in 2009's "Transformers: Revenge of the Fallen.")

LaBeouf, 28, has become increasingly odd and erratic over the past couple of years. The former child star turned heads back in February when he showed up to the Berlin premiere of his film "Nymphomaniac" with a brown paper bag over his head, which read: "I am not famous anymore."

The actor's most recent public meltdown occurred at New York City's Studio 54 theater on June 26. He was arrested and escorted out after causing a disturbance during a performance of Michelle Williams and Alan Cumming's Broadway show "Cabaret." Following the incident, LaBeouf's rep told Us Weekly that the star was seeking treatment for alcoholism.

As for his relationship with Fox, LaBeouf previously claimed that the two hooked up on the set of "Transformers" back in 2007 while Fox was on a break with then-boyfriend Brian Austin Green. "Look, you're on the set for six months, with someone who's rooting to be attracted to you, and you're rooting to be attracted to them," he told Details magazine in June 2011.

"I never understood the separation of work and life in that situation," he added. "But the time I spent with Megan was our own thing, and I think you can see the chemistry onscreen."
