Hayden Christensen's daughter truly is his little princess!

The notoriously private actor revealed why he and Rachel Bilson named their daughter Briar Rose while promoting his new movie, "90 Minutes in Heaven," which also starred Kate Bosworth.

"There's a Disney reference there, I suppose, the original Sleeping Beauty is called Briar Rose," he told the host of Hallmark Channel's "Home & Family," reported Us weekly.

Christensen revealed that he was a big Disney fan, but it was Bilson who fell in love with the name. "We both love all things Disney - but Rachel especially was very keen on the name," the actor said. "We have Disney songs playing around the house 24/7 right now."

Bosworth noted that the name was a perfect choice for the couple's daughter. "Rachel is such a little Disney princess. I love her," the actress said.

Less than two weeks after Bilson shared an adorable photo of their baby girl and Christensen, the actor gushed about his new father role. "I have this little angel in my life now and Rachel and I are so thrilled," he told E! News. "We don't sleep as much as we used to, but it's all so worth it."

Bilson and Christensen welcomed their daughter into the world last November, reported People magazine.
