Now this is a couple of studly siblings.
Big red-carpet premieres have been family affairs for these guys in the past, but Liam skipped the New York premiere of Chris' racing drama Rush to avoid any awkward Q&A right after splitting up with Miley Cyrus.
And while this wasn't Liam's first red carpet since the breakup, it was his first film premiere.
It's high time for the 23-year-old actor to get used to the spotlight again, however: The Hunger Games: Catching Fire hits theaters Nov. 22, and junkets, TV appearances and red carpet banter will be required.
As for big brother Chris, the Thor hunk admitted to E! News at the Rush premiere that Liam missed that he and wife Elsa Pataky were "lucky" that the media let them fly under the radar, comparatively speaking.
"You never know why the media is attracted to one thing or not interested in one thing," Chris said. "I've been lucky, my wife and I live a pretty normal existence."
No kidding: The Australian actor even said in the latest issue of Details that he doesn't quite remember his wedding anniversary.
"Uh, I should know the answer to this. There's a bit of a dispute...So yeah, answer about the date of my wedding: somewhere in December."
How "normal" is that?!
