Britney Spears and Kevin Federline have welcomed their second son together, a source close the family has confirmed to PEOPLE.
The baby boy, who was born just before 2 a.m. Tuesday at a Los Angeles hospital, was delivered via a scheduled C-section.
"Kevin had a smile on his face. He looked happy and upbeat," says an observer.
The whole thing, says a source, was smooth just as the mom-to-be had predicted to PEOPLE back in August, saying childbirth "will be a piece of cake."
Spears, 24, and Federline, 28, already have a son, Sean Preston, who was born Sept. 14 last year. For Federline, the new arrival is his fourth child. He also has a daughter Kori, 4, and son Kaleb, 2, with actress Shar Jackson.
Spears first publicly confirmed this pregnancy during a May 9 visit to the Late Show with David Letterman. "Don't worry, Dave, it's not yours," she joked to the host, who responded: "Oh. Well, I think that's good news for both of us."
The birth of their second child comes as Spears and Federline celebrate their second anniversary: The couple wed on Sept. 18, 2004. The pair began talking about starting a family soon after. "I can see myself as a mom. Next year at 23, I am so there," she told PEOPLE shortly after the wedding.
Just four days short of the couple's first wedding anniversary, she had accomplished that goal by having Sean Preston.
The timing of baby No. 2's arrival may have been a surprise Spears has said the pregnancy wasn't planned but expanding her brood was never a question for the domesticity-craving pop star. Sean Preston "is going to be traveling on the road with me, so I think it will be good to have (a sibling) there with him," she told PEOPLE last month.
For Federline's part, the aspiring rapper told PEOPLE after his performance at the Teen Choice Awards last month, that he planned to take time off until after the baby was born. "I'm really going to kick back and wait and see when this baby is going to come, spend my time with my family and my wife," he said.
As for being pregnant a second time so quickly after the first, Spears said she's been happy to indulge her cravings for ice chips and chocolate, but having gained some 40 lbs., has also been frustrated at not having time to get back into the shape she was before becoming a mom. "I feel like I've been pregnant for 10 years!" she said.
Spears vowed that after the birth of her second child she'd get back to the gym and back to work. "I'm definitely going to start working out in a huge way," she told PEOPLE last month.
Plus, the singer, whose last original album was 2003's In the Zone, is working on a new album due next year, which she describes as "cooler than ever fun, upbeat and sexy."
Now, lets see if she can avoid getting pregnant again - for at least a year anyway! Its nice she had a boy, I bet her boys will be great playmates since they are so close in age. I had a feeling it was going to be another boy.
Britney is still the sexiest according to British men
Esquire Magazine may have named Scarlett Johansson 'Sexiest Woman Alive' here in the states, but accross the pond, it's sexy former pop princess, Britney Spears, who remains the big favorite with males 18 to 49. "Spears, 25, topped the British version of Hello Magazine's first ever list of the '100 Sexiest Women in the World', beating out the likes of Beyonce', Sienna Miller, Kate Beckinsale, Christina Aguilera, Jessica Alba, Lindsay Lohan, Eva Mendes, Jessica Simpson, and even Miss Johansson." Oddly enough, perrenial favorite, Angelina Jolie failed to make an appearance on the list, while somehow, former 'Baby Spice, Emma Bunton, managed to come in at #3... I guess back in England, she's still a pretty hot commodity. The men polled stated that it's her past as a teen pop temptress, often draped in barely-there clothing, and her more recent Harper's Bazaar naked-and-pregnant spread last June that has made her top pick out of 100 famous women. Scarlett Johansson, however, finds herself landing all the way at #27, behind London TV personality Cat Deely.
Spears, who just gave birth to her second son, Sutton Pierce, is looking to get back to her sexy shape, and has been working hard in the studio on her long awaited comeback album, which would actually be her first full-length album of original material since 2003's 'In the Zone'.
ExtraTV.com: Britney Spears is showing off her new post-baby body, and the pop princess' sudden slim down has landed her on the cover of this week's Us Weekly.
Us Weekly's Katrina Szish told us that Britney lost 26 pounds of baby weight in just one month! So what is her secret? "Britney is working out twice a day," Szish revealed. "Britney's also traded her fast food diet for lots of smaller, healthier mini-meals, and she's also cut out white flour altogether."
While we caught a glimpse of the old Brit we know and love, we caught her hubby Kevin Federline getting his work out on at the WWE's Monday Night Raw.
