Former California

Governor Arnold Schwarzenegger said on Monday that his 13-year-old son,

Christopher, is improving as he recovers from injuries suffered when he

was hit by a large wave at the beach.

"Thanks for all your support

for Christopher," Schwarzenegger wrote in a Twitter post. "It means a

lot to me & to him. He's doing much better & we'll have him back

at full speed soon."

The celebrity

news website TMZ.com has reported the youth was severely injured when

he was hit by a large wave while surfing or boogie-boarding last weekend

in Malibu, suffering multiple broken bones and a collapsed lung.

Schwarzenegger

and his estranged wife, Maria Shriver, issued a joint statement last

week saying only that their son, the youngest of their four children,

had been hurt in a beach accident but was expected to make a full

recovery.

Shriver filed for divorce

from Schwarzenegger on July 1, weeks after the Austrian-born former

bodybuilder and film star publicly admitted to fathering a child out of

wedlock with a member of the family's household staff over a decade ago.
