"I'm in love ... I like the fact that he's very stubborn and he's stuck in his ways.," she told Entertainment Tonight.

Britney also revealed that her father Jamie Spears ran a background check on David, when the couple started dating after meeting through mutual friends.
"My dad's a little crazy like that," she joked.
While their romance is still in its early days the Hit Me Baby One More Time singer has said she would consider marrying and having more children "if the timing was right." The songstress already has two sons, Sean Preston, seven, and Jayden James, six, from her marriage to dancer Kevin Federline.
The Louisiana-born star struck up a romance with David two months after she announced her separation from former agent Jason Trawick in January.
Britney released a statement reading: "Jason and I have decided to call off our engagement. I will always adore him and we will remain great friends."
The sad news came just over a year after the pair announced their plans to marry. The couple proved the split is an amicable one when Jason, 41, spoke highly of his former partner and her family, saying: "As this chapter ends for us a new one begins. I love and cherish her and her boys and we will be close forever."
