Beyonce is still pregnant with her first child, according to her sister Solange. The rumor mill went into overdrive at the weekend with reports that the R&B superstar and husband Jay Z had welcomed Tiana May Carter at St Luke's Roosevelt Hospital - a private facility in New York. The speculation was quickly shot down by Solange Knowles, the pop star sister of Beyonce, who tweeted on New Year's Day, "Shout out to my sister for being The cutest pregnant woman ever!" Billboard.com had previously reported how the heavily pregnant singer was spotted having dinner with her husband in Brooklyn on New Year's Eve, before the pair headed to her sister's party to celebrate 2012. The former Destiny's Child star has already confirmed to Australian television show Sunday Night that she is expecting to give birth in February, though many assumed she was simply directing attention from a possible birth between Christmas and New Year. The singer first announced news of her pregnancy on the red carpet at the MTV Video Music Awards in August 2011. 'Beyonce is pregnant' immediately became a trending topic on Twitter, sparking a record-breaking 8,868 tweets per second about the announcement. A source close to the singer has since confirmed to People magazine that she is still very much pregnant, saying, "She was definitely a pregnant lady that night (New Year's Eve). They sat side by side and had a cosy and intimate dinner. They seemed to be having a lovely time".
