Beyonce's Sister Confirms That the Singer Is Still Pregnant

The pop artist's sibling Solange Knowles set the record straight on Twitter regarding rumors to the contrary.Rumors of Beyonce's baby birth have been greatly exaggerated.

The singer's sister, Solange, shot down Twitter-fueled chatter that she delivered a baby girl last week, and named her Tiana-May Carter. 

"Shout out to my sister for being THE cutest pregnant woman ever!" wrote Solange in a coy tweet on Sunday. Further evidence: a still-pregnant Beyonce and her rap mogul-husband Jay-Z (real name: Shawn Carter) were sighted having dinner together in New York City's Brooklyn borough on Saturday and then ringing in the New Year at a Solange-hosted house party. 

As for those rumors, they snowballed Friday following dubious headlines on the gossip website Media Take Out (via Gawker), claiming Beyonce was scheduled to go into labor in the Big Apple on Wednesday after reserving St. Luke's-Roosevelt Hospital's "luxury labor and delivery floor" for the occasion. The site claimed it had confirmation from a pair of nurses at the hospital, but they've been wrong before: In 2010, Media Take Out sparked false Beyonce pregnancy alarms and, last year, it cited a source as claiming that the singer wore a faux baby bump. (Beyonce denied the allegations.) 

THR reached out to representatives for Beyonce and Jay-Z, but they didn't respond to requests for comment.

"We were so good as friends that romantically, we just clicked right away. There was no adjustment period," Gonzalez-Jones told PEOPLE earlier this year.

Impending fatherhood "is sinking in" Martinez says, admitting that he can't believe all of the good things that have happened in the past year.

"2011 has been full of a lot of surprises and opportunities and ultimately, a lot of blessings," says Martinez. "Diana and I were just asking ourselves, 'How is 2012 going to top 2011?' Well, we have our answer!"
