Beyoncé allegedly snubbed Rihanna at her visual album release party by not extending an invite.

According to HollywoodLife.com, the "Grown Woman" singer threw a celebratory bash at Dave & Busters after her concert in Brooklyn, NY. on Dec. 19. Beyoncé celebrated with her A-listers pales including like Rihanna's ex rapper Drake, Jessica White, stylist Ty Hunter, Alexander Wang, Luke James and J. Cole.

However, the "Diamonds" singer was nowhere in sight. According to Mediatakeout.com, Rihanna was caught partying just down the block. Click here to view the photos.

An inside source told the website Rihanna was "furious" that Beyoncé would drop the album on Dec. 13. She allegedly felt Beyoncé wanted to upstage the release of her video for "Monster" with Eminem.

"Rihanna and Beyoncé have always had a very cordial [relationship], but they are definitely competitors," the source said. "I think Beyoncé is jealous of Rihanna. First there were those Jay Z rumors, and lately people are acting like Rihanna [is] the top girl in the game... [I think] Beyoncé definitely pulled a power play and let Rihanna know who the Queen is."

Neither Beyoncé nor Rihanna have confirmed any beef with each other, but if Beyoncé did pull a "power play" it was a good one. Beyoncé's self-titled visual album has reportedly sold more than 1 million downloads in less than a week.

"I didn't want to release my music the way I've done it. I am bored with that. I feel like I am able to speak directly to my fans. There's so much that gets between the music, the artist and the fans. I felt like I didn't want anybody to give the message when my record is coming out. I just want this to come out when it's ready and from me to my fans," Beyoncé said in a statement.
