OTRC: Beyonce and Jay-Z welcome baby girl, say reports

Beyonce and Jay-Z welcomed a daughter, baby-bumping the music power duo to a trio Saturday night.

According to a report by E! News, sources confirmed the singer gave birth via scheduled C-section at Lenox Hill hospital in New York.

The baby's name was originally reported by E! as Ivy Blue. The New York Daily News says the girl's name is Blue Ivy.

Update: 9:00 a.m. Actress Gwyneth Paltrow confirmed the baby's name as Blue Ivy when asked by a follower on Twitter.

"RT @Sparrow_Teague @GwynethPaltrow is it ivy blue, or blue ivy? so confused..It's Blue Ivy Carter," Paltrow wrote.

The actress previously sent out a Tweet welcoming the baby saying, "Welcome to the world Blue! We love you already."

Spokespeople for both Beyonce and Jay-Z have not commented on the birth or the name of the child.

Beyonce's sister Solange Knowles shared her first thoughts of the new baby early Sunday morning tweeting, "The most beautiful girl in the world."

The couple's close friend and music mogul Russell Simmons celebrated the new arrival by tweeting, "congrats to my good friends Beyonce and Jay-Z."

Rihanna also gave a shout on Twitter, "Welcome to the world princess Carter! Love Aunty Rih."

The 30-year-old singer announced her pregnancy during the 2011 MTV Video Music Awards in August. During her 2011 MTV VMA performance she told the audience, "I want you to feel the love that's growing inside me." At the end she opened her sequined tuxedo jacket and rubbed her stomach, to the delight of the crowd.

It is the first child for the singer, who is married to 41-year-old rapper Jay-Z, whose real name is Shawn Carter. The couple got married on April 4, 2008. The nuptials were so secret that no photos or video from the event were released. The couple got married with a close circle of 40 friends and family members after dating for six years.

Rumors that the pop star had given birth in December sparked a Twitter frenzy , but the craze was never backed up by any evidence.
