Jessica Simpson gives birth

Jessica Simpson has given birth to her daughter Birdie.

The 39-year-old singer and actress - who already has daughter Maxwell, six, and son Ace, five, with husband Eric Johnson - has reportedly welcomed her third child into the world, a daughter named Birdie Mae Johnson.

The news was reported by People magazine, who claim Jessica's representative confirmed the happy news, saying the tot was born late on Tuesday and weighed 10 lbs., 13 oz.

Earlier this week, sources said the 'Blonde Ambition' star was ready to give birth any day now, and had her "hospital bags packed" and waiting.

An insider said: "Jessica is definitely uncomfortable. This has been a tough pregnancy but she knows it will all be worth it when she's holding that little baby. Her hospital bags are packed. Everyone is trying to be patient, but the family is so excited and counting the minutes until the baby is here."

Meanwhile, Jessica previously admitted she "doesn't understand" how she got pregnant again.

She admitted: "I thought about having another baby, but I didn't really know that it could actually happen. We definitely always love to practice. We actually weren't practicing very much that month so I don't understand. We try to figure it out. This might be a miracle baby."

But despite her confusion over the new arrival, her children were "so excited" to be a big brother and big sister.

She added: "They're so excited because they're only fourteen months apart, so they didn't get to experience the excitement of each other. But when I told them that we're having another baby, I know that they'll remember that for the rest of their lives. They are most excited about learning how to do the swaddle. Maxwell, my daughter is just so happy that it's a girl. They ask me the craziest questions that I can't say on TV ... 'How does the baby come out?' 'Where does the milk come from, I don't understand!' I'm a little bit too honest, and Eric's like, 'I don't think we need to give out ALL the information, Jessica. So, I'm scaring my kids, I think."
