How well do you know Justin Chambers (Alex Karev)? Us Weekly has the Grey's Anatomy actor sharing 25 fun facts about himself, and some surprised even us!

We don't want to steal all of Us's thunder, though, so we've selected some of our favorite trivia!

"I once had a pet goose, George," Justin reveals in the article. Um, was its last name O'Malley? In any case, we're sure Justin treated that bird better than Alex treated our dearly-departed 007!

Justin continues: "I am a fraternal twin who has fraternal twins." His twin brother is named Jason, and Justin's twins (two of his five children) are Maya and Kaila.

"I have a love-hate relationship with hot yoga," Justin says, referring to the practice of performing yoga in steamy conditions. We gotta say, the image of Justin flexing and stretching while all hot and bothered is not one that we mind envisioning.

"My oldest child is now in college," Justin says of his daughter, Isabella. Just imagine yourself moving into your dorm room on your first day of college and finding Alex freakin' Karev helping your new roomie make her bed.

And finally: "Last year, I took an acting class taught by my childhood crush, Lindsay Wagner, just so I could meet her." Not like Justin needs any help with his emotin'! Lindsay, by the way, is a 64-year-old actress best known for her role in the '70s series The Bionic Woman.

Go check out Us Weekly to read all about his "fat, old beagle," his favorite reality TV shows, his tattoo, his childhood ambitions, and more!
