Mariah Carey and Beyoncé Knowles joined forces on Thursday night to promote a good cause. The two popped up together at the Heartview Global Foundation's "Give For the Heart" Dinner in LA and managed to snap an ultraglam Instagram picture in the process. "Two girls, one cause," Mariah captioned the post. It's been an absolutely monumental week for Beyoncé, who dropped a new single and music video on Saturday and shut down the Super Bowl and announced a tour on Sunday. Mariah, on the other hand, recently got engaged to her boyfriend, James Packer, and continues to give us a look into her opulent mom life on Instagram. All we know is, we would've given anything to be a fly on the wall in the same room as these two.
