How romantic! Bones actor TJ Thyne is engaged to his girlfriend Leah Park -- and he documented the entire proposal! The 38-year-old star popped the question to his longtime love outside a German castle on Monday, Dec. 30.

"Our walk…our trail," Thyne tweeted at the time. "SHE SAID YES!!!" The actor posted several pictures of the special moment, including a picture of himself on bended knee asking for Park's hand in marriage, several pictures of the couple, and close-up snapshots of the model and her beautiful diamond ring. "Our heart still burning through the night :0)!!" he added.

In one photo, Thynes and his bride-to-be also stood in front of a horse and carriage, with a stunning German castle backdrop. Thyne donned a dark suit, while Park wore a tight-fitting red dress.

Thynes has played Dr. Jack Hodgins on the FOX series since 2005. He's also appeared in films Erin Brockovich, Ghost World and How the Grinch Stole Christmas.
