The actor and former governor of California is in stable condition.

Arnold Schwarzenegger has undergone heart surgery, but it was planned, The Hollywood Reporter has confirmed. 

The 70-year-old actor and former governor of California is in stable condition and is awake. 

Earlier reports that Schwarzenegger had emergency open-heart surgery were wrong. 

The actor and former Mr. Universe had an pulmonic valve replaced, which he originally had done in 1997, according to his spokesman, Daniel Ketchell. A medical team was on stand-by in case something went wrong, which is procedure, but they were not needed, Ketchell said in a statement.

Schwarzenegger is slated to appear in Expendables 4 and the upcoming Terminator installment. 

Schwarzenegger served as governor from 2003-2011.

On Monday, Schwarzenegger tweeted about his recovery: 

It’s true: I’m back! I went to sleep expecting to wake up with a small incision and woke up with a big one - but guess what? I woke up, and that’s something to be thankful for. Thank you to the doctors & nurses. And I’m truly filled with gratitude for all of the kind messages.
