Britney wants another baby.

The 31-year-old mother of two told Mario Lopez on "Extra" that she’s pining for a daughter, Us Weekly reports.

"I'm very jealous 'cause you have boys," Lopez told Spears. He has a two-year-old daughter and a baby on the way.  Spears said, "Aww, I want a girl!"

"Oh, you do want a girl! So later on, maybe a little girl?" Lopez asked. Spears answered, "Yes!"

Spears says her sons, Sean, 7, and Jayden, 6, have made it hard for her to stay in shape, ABC News reports.  

“When the [the boys] come over, the snacks are constantly piling up, and I constantly have to feed them. I’m like, ‘Jesus, I want fried chicken too!’”

But Spears hasn’t let the temptation get to her. The former "X-Factor" judge donned a white bikini for the cover of Shape magazine’s June issue.

“I’m doing 90 minutes of yoga twice a week in addition to a lot of cardio -- hour-long sessions three times a week with my trainer, Tony Martinez,” she says about keeping fit. The star also follows the Nutrisystem program, where she has a shake for breakfast and lunch with a dinner filled with protein and vegetables, she told Shape magazine.

Spears’ baby news might be a product of good timing. This weekend, Spears was spotted with a gold ring on her engagement finger, E! Online reports. She has been dating her boyfriend, David Lucado, since Valentine’s Day.
