The former wrestler and Fast Five star insists he owes his success to his beloved mother Ata, who struggled to make ends meet when Johnson was a teenager, and over the holidays the 40 year old splashed out on a special gift - a white Cadillac SUV, complete with a big red bow.
Posting a series of photos of his mum's surprised reaction on his Facebook.com page, he wrote, ""At 14, I saw my mom crying about our only car being repossessed. This felt good, Merry Christmas, Mom.""
And a source tells the National Enquirer, ""Dwayne has a heart of gold and he lives his life like that every day. He has definitely done his mama proud.""
