Beyonce fans hoped the '4' creator would pop out Jay-Z's offspring this weekend, however, it looks like the singer hasn't gone into labor just yet. The 'Countdown' performer's sister is setting the record straight about rumors the star gave birth within the last few days.

Solange Knowles singled out her big sister in a post via her Twitter page. "Shout out to my sister for being THE cutest pregnant woman ever!" she wrote Sunday (Jan. 1). Apparently, Beyonce is still very much sporting a baby bump and welcomed 2012 without going into labor.

The 25-year-old also posted about partying the night away with her brother-in-law Hov. "Shout out to my brother for being in the champagne business! Shout out to my brother for actually pouring the champagne."

Even though Bey didn't make a public appearance on New Year's Eve, she still managed to perform on the small screen. The 'Dick Clark New Year's Rockin' Eve' special on ABC aired a pre-taped performance of Beyonce belting out 'I Am Here,' which she also did during the Glastonbury festival in London earlier this year.

Last week, a story emerged claiming that the former Destiny's Child frontwoman had checked into New York City's St. Luke's Roosevelt Hospital in preparation for delivery. According to reports, the multi-Grammy winner reserved the same hospital suite used by Alicia Keys when she gave birth to her son, Egypt, last October. Staff members were also said to have been put on alert regarding the arrival of a "celebrity VIP."

Other than gushing over the prospect of becoming a mother, Beyonce has kept mum on many of the details surrounding the birth of the baby. Her fellow Destiny's Child group member, Kelly Rowland, let it slip that the 30-year-old was expecting a girl, but she has yet to confirm or deny the sex of the baby.
