Sorry, girls, Chad Michael Murray is officially off the market. And sorry, guys, his co-star on One Tree Hill, Sophia Bush, is also off the market.

The 22-year-old Murray recently popped the question to Bush, also 22, who plays a bad-girl cheerleader whose lustful crush on his brooding basketball player character is unrequited.

In real life, however, Murray is smitten by the woman he's been dating for less than a year, reports E!Online.

"She's perfect," he said. "She keeps me inspired, and she complements me very well."

The pair got engaged two months ago in Australia, where Murray was shooting a remake of the horror film House of Wax, co-starring Paris Hilton.

A true romantic, Murray treated his bride-to-be to a day at the spa, followed by shopping and dinner before returning home and producing a ring that he helped design.

"I couldn't bring her home until the sun went down because I had 500 candles and 20 bouquets of roses set up," Murray said. "Then I had this big light strand on a tennis court with a message spelled out to her that you could see looking down from the balcony of our 18th-floor penthouse."

Though Murray won't reveal exactly what the message said, it worked. The pair will tie the knot next year.
