The two recently hung out together at a gala held by the Heartview Global Foundation, a heart disease research group, in Los Angeles. Both showed major cleavage in gorgeous dresses. Bey, 34, wore a sleek ivory, caped number and pearl drop earrings. Carey, 45, sported a semi-sheer, lace glittering gown, which she pared with a sparkling cuff and her massive diamond engagement ring.
"Two girls, one cause," Carey said on Instagram Thursday, alongside a photo of the two.
