His mom and dad are separated, but son Patrick Schwarzenegger isn't worried -- because they drive Hummers!

"Appreciate all your messages. Small speed bump I'n life, luckily we own hummers, we will cruise right over it. All will be okay. #peace," Patrick tweeted Tuesday morning.

Interestingly, Patrick's username on Twitter has his father's last name while his profile name is listed as Patrick Shriver, using his mother's maiden name.

A recent switcharoo?

Arnold Schwarzenegger and Maria Shriver announced their separation after 25 years of marriage on Monday evening by releasing a joint statement.

But Patrick, only 17, doesn't seem worried about how it will impact him.  He's already on the road to success as a model -- he's just signed with L.A. Models -- businessman, and party animal.

He hangs with Tallulah Willis -- daughter of Bruce Willis and Demi Moore -- he told Details. The trendy men's mag has a lengthy profile on the hunky teen in its current issue.

Patrick's Twitter mates are Selena Gomez and Kendall Jenner, he also revealed.  And he talked about the for-profit Halloween party he threw last year. Six hundred kids attended, paying $20 each, and "we flew in a rap band from the East Bay called The Pack," Patrick said, adding that cops busted the party for underage drinking.

His parents' response?  "They're glad I had fun with it but they weren't happy with how it was portrayed in the media."

Word to Patrick: Get used to it!
