They say a picture's worth a thousand words, and this shot of Gabrielle Union and Dwyane Wade certainly speaks volumes. The longtime couple made things official on Saturday, Dec. 21, when Wade, 31, popped the question in Miami, Florida. 

The NBA player proposed with a 8.5-carat diamond ring by Jason of Beverly Hills, and the 41-year-old actress was clearly overjoyed. In the photo, the basketball star is still down on one knee as the emotional Think Like a Man actress cradles her future husband's head with her new bling sparkling. 

The A-List couple has been dating for four years, and though they took a brief break earlier this year, they're back and stronger than ever. 

Union tweeted a picture of the giant diamond, followed by, "Maaaaaannn... I'm floatin! Thank you SO much for all the love, well wishes & support!"

She went on to say she was "truly caught off guard," which was why her hands "were ashy… and yes my nails aren't done." 

The couple started dating in 2009 and has been very open about their relationship. 

"She makes my eyes sparkle," Wade said of Union during Oprah's Next Chapter back in July 2012.
