R&B royalty Beyonce and husband Jay Z are rumored to be expecting their second baby with entertainment news outlets referring to her latest Instagram posts as proof.

Rumors of baby No. 2 come in the wake of a year's worth of rumors that Beyonce and Jay Z had been struggling with their relationship, which allegedly almost led to divorce. However, the split rumor was immediately slammed by the songstress' mother, Tina Knowles, says Celebuzz.

According to CelebDirtyLaundry.com, an issue of OK! Magazine would be featuring a story on Beyonce's possible pregnancy after Blue Ivy, noting the growing bulge in her belly when the couple watched last month's basketball match between the Brooklyn Nets and the Cleveland Cavaliers.

"The couple [Jay Z and Beyonce] caused triple takes at a December 8th game as Beyonce tried in vain to cover up what appears to be a growing baby bump," the report read.

Aside from Beyonce and Jay Z, Kate Middleton and Prince William were also present to watch the matchup during their visit to New York in early December, a past report from The Inquisitr indicated.

After chatting with the Duke and Duchess of Cambridge during break time, Beyonce reportedly spent the rest of the game satisfying her pregnancy cravings.

In a more recent report, Celebuzz said that the "Listen" songstress' baby bump seem to have become more prominent in a photo she posted on her Instagram account.

The award-winning singer has recently uploaded photos of their Asian vacation on Instagram, where they visited Cambodia's ancient tourist destination, the Buddhist temple of Angkor Wat.

According to The Inquisitr, the singer's recent outfit choices may have contributed to the pregnancy rumors in a way, as she was frequently seen wearing loose-fitting blouses that cover her entire belly, perfect for people hiding a baby bump.

A report from the Daily Mail UK compiled photos of the couple enjoying the warm atmosphere in the country, where the 33-year-old hitmaker sported a loose animal print top matched with army-inspired trousers.

This led the online community to speculate that she was trying to hide her baby bump.

"Is it me or Beyoncé look pregnant," @_AlexisCharles wrote which was echoed by @RavennaWhite who posted that the singer "don't look nothing but pregnant" in the photo.

Another fan with Twitter ID @jiggarella_  cleverly came up with baby no. 2's name based on the name of the couple's first child, Blue Ivy: "Yaaaaas!! RT @_Mpho: Purple Lavender is on the way"
