Britney Spears hasn't said much about her current boyfriend, David Lucado, but apparently things are quite serious between them.

The pop star told "Entertainment Tonight" that they have discussed children, though walking down the aisle isn't a definite.

"I'm in love. … I like the fact that [David] is very stubborn and he's stuck in his ways," Britney told "ET" in an in-depth interview that begins airing tonight and concludes Friday. "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."

The 31-year-old singer confirmed a previous report that her dad actually ran a background check on Lucado before they started dating nine months ago but said that she is not upset about it.

"That is true. My dad's a little crazy like that," she told "ET."

The singer also revealed that she's told Lucado that she wants more children but said that she's not sure if she'll actually get married again.

Spears has two sons with her ex-husband, Kevin Federline. In 2004, she was wed to childhood friend Jason Alexander for 55 hours before the marriage was annulled. The pop star was first seen with Lucado on Valentine's Day, about a month after she broke off her engagement to Jason Trawick.

In the interview, Spears also discussed her upcoming album "Britney Jean," which comes out next week.

"I would say [the album] was kind of like therapy for me. It just kind of transformed me," she told "ET." "As you write something your perspective changes. … I think there are periods in everyone's life where you get kind of reclusive, your creative outlet is cut off. Then sometimes it flows and you're like, 'Oh my God, this is what I need to be doing,' [which makes] it easier for you to be the artist that you want to be."

As for her upcoming Las Vegas residency at Planet Hollywood, which kicks off at the end of December, Spears said she decided to do it because her last tours have been so "grueling" and "insane."

"It just felt like the ideal thing to do," she said. "So, I'm really excited about it. It's going to be different, but I'm excited."
