Pregnancy rumors are swirling around Beyoncé after a public appearance in Brooklyn. Reuters

Beyoncé might be pregnant with baby No. 2, multiple reports have claimed. The “Drunk in Love” singer has been wearing loose clothing lately -- like when she met Kate Middleton and Prince William at the Brooklyn Nets game Monday -- and some believe that’s because she might be hiding a burgeoning baby bump.

When Beyoncé strutted across the basketball court to great the royal couple, wearing a blouse that was bigger than normal, the rumors that she was pregnant ignited. Gossip about the singer expecting another child first emerged months ago when Jay Z apparently changed the lyrics to one of his songs to say “ 'Cause she pregnant with another one.”

Adding to the pregnancy speculation, Gawker said Beyoncé did not drink beer at the Nets game. In Touch Weekly wrote she looks like she might have put on a little weight.

The bigger-than-normal clothing and non-beer-drinking was all it took to send social media into a frenzy. Many are convinced Jay Z and Beyoncé will give 2-year-old daughter Blue Ivy a sibling.

If she is pregnant, it’s apparently been the couple’s plan all along. “If all goes well they’ll start trying for a baby before Christmas,” a source told OK! magazine. “She wants to be pregnant by spring.”

The couple recently battled divorce rumors after the rapper, 45, allegedly cheated on Beyoncé, 33. But the duo seemed to have moved past their alleged differences and “renewed” their vows. “They’ve worked through a lot of their problems and have a string of rules they’re sticking to to keep the marriage alive,” the source told the news site.

The singer has remained quiet on the pregnancy rumors. She hasn't posted to Instagram for over a week and hasn't used her official Twitter account for more than a year.
