The 31-year-old popstar talked about her boyfriend of almost nine months in a candid interview about her love life and music career on US chat show, Entertainment Tonight.
"I'm in love," she said. "I like the fact that David is very stubborn and he's stuck in his ways.
"He's just a simple man. I adore him. He's really funny and he's really passionate. I love the fact that anything he's involved in he's passionate about and it's contagious."
Britney, who will perform 50 shows a year when she starts her two-year residency at Planet Hollywood in Las Vegas, also confessed that her father ran a background check on David before giving his seal of approval!
"My dad's a little crazy like that," she added.
Britney, who is currently promoting her new studio album Britney Jean, confirmed that she was introduced to David through mutual friends.
The couple were photographed together for the first time on Valentine's Day in February, a month after her split from fiancé Jason Trawick.
