Former Malcolm in the Middle child star Frankie Muniz, now pursuing a music career, has some sharp words for fellow actor Shia LaBeouf (Wall Street, Transformers, Disturbia) calling him “creepy” for talking about Muniz in recent interviews.

La Beouf, also a former child star (Even Stevens), mentioned Frankie Muniz in a recent chat with American radio program The Bert Show.

When the host asked LaBeouf about his movie success, he replied:

“While that’s flattering as hell, you could have put Frankie Muniz into any of the movies I’ve been in and those movies still would’ve still been number one.”

When LaBeouf was asked whether he feared repercussions over that comment if he were to see Muniz at say, a party, he replied, “I don’t go to many parties… and I really don’t hang out in Frankie Muniz-type zones.”

Muniz is allegedly unhappy about LaBeouf’s comments and took to Twitter to vent, writing:

“Dear Shia LaBeouf. It’s getting creepy the fact that you can’t stop talking about me. It’s been 12 years now. I don’t know you. Thanks.”

The dueling duo  were previously engaged in a public feud back in 2003 when LaBeouf accused Muniz of “looking down” on him at parties.

He said, “I used to see him at premieres and stuff and it would always be like he was looking down on me. And then it turned into we’re equal, and then it turned into, ‘Oh Frankie, I know that guy.'”

What do you think? Did Frankie really dis Shia back in his hey as the more prominent child actor? Or is Shia being insecure about imagined slights?

Either way – looks like one of these former child stars is accused of being a Big Fat Liar.  Sorry – just had to use that movie title in here somewhere!
