Fans are convinced Beyoncé, who's pregnant with twins, revealed the gender of the babies — with her earrings!

On Monday, March 13, the singer released a series of photos on her website from stepfather Richard Lawson's birthday party, and eagle-eyed members of the Beyhive were to quick to the note that the oval earrings she wore to the bash were the same ones she rocked in her 2008 music video, "If I Were a Boy."

Twitter users immediately began speculating over whether this means the 35-year-old and hubby Jay Z are expecting twin boys. Other fans think the first bump photo she released signals that she's expecting a boy and a girl given the pink bow on her bra and her blue underwear.

The Grammy winner's followers have been looking for gender clues ever since it was discovered that Bey had dropped hints about her two bundles of joy before announcing the pregnancy on Feb. 1. Before the holidays, the "Drunk in Love" hitmaker showed off an itty bitty baby bump in a low-cut navy blue Jitrois dress while holding up two fingers.

A source previously told Life & Style that the new additions saved the power couple's marriage. "They both wanted two children, and made that decision when they got married," the insider revealed. But their struggles to conceive after the birth of daughter Blue Ivy, 5, caused problems for the duo. "Everyone working with them felt like you could cut the tension with a knife. The pregnancy has renewed their relationship."
