Actress Gabrielle Union has double the reason to celebrate the holidays - she is engaged to her basketball star beau Dwyane Wade.

Christmas came early for the Bring It On beauty after Miami Heat ace Wade popped the question.

Union, 41, broke the news to fans on Saturday (21Dec13), when she uploaded a photo of the massive diamond ring on her Instagram.com page, alongside the caption, "Sooooo this happened... Yessss (sic) @dwyanewade".

The couple has been dating since 2007.

It will be the second marriage for both stars. Union was previously wed to American football player Chris Howard, but they divorced in 2006 after five years as husband and wife, while Wade, 31, married his childhood sweetheart, Siohvaughn Funches, in 2002. They split in 2007, but their divorce turned nasty and it wasn't finalised until 2010. Wade was awarded sole custody of their two young sons in 2011.
