"Malcolm in the Middle" star Frankie Muniz tweeted that he was hospitalized Friday for a "mini stroke."

"I was in the hospital last Friday. I suffered a 'Mini Stroke,' which was not fun at all. Have to start taking care of my body! Getting old!" wrote the actor, who turns 27 on Wednesday.

The "Malcolm in the Middle" star now plays drums for the band Kingsfoil, and has tweeted details of the band's upcoming dates since the hospitalization.

A representative for Muniz did not immediately respond to a email inquiring about the nature of the "mini stroke," its cause, and Muniz's current condition.

In February 2011, Phoenix police were called to the home of Muniz and his girlfriend, who told officers that the actor had struck her and put a gun to his own head, possibly with suicidal intent.

After finding no signs of injury, police confiscated Muniz's .380 semi-automatic gun and issued disorderly-conduct warnings to Muniz and his girlfriend. They said the incident wouldn't be  investigated further.

Muniz' rep denied at the time that he had struck his girlfriend or was suicidal. Muniz told police the gun was not loaded and that he had picked up its case, but not the gun itself.
