Miami Heat guard Dwyane Wade decided to take his relationship with actress Gabrielle Union a step further on Dec. 21 when he finally popped the question to her in Miami. Wade and Union had been dating since 2009 and even sent out Wade-Union Christmas cards this year -- so it looks like they were already serious about their relationship. Right after the proposal, the beauty captioned: "Sooooo this happened…#Yessss," with a photo of her custom 8.5 carat cushion-cut engagement ring on Instagram. Her basketball star beau posted the same picture with the caption, "She said YES!!! @gabunion."
