during the NASCAR Sprint Cup Series Daytona 500 at Daytona International Speedway on February 23, 2014 in Daytona Beach, Florida.

Dale Earnhard Jr. just let a major Jimmie Johnson secret slip

Now he's done it! Dale Earnhardt Jr. let the cat out of the bag.

Apparently Mr. Seven-time himself, Jimmie Johnson  is opening a restaurant in Charlotte. The restaurant is called SouthBound and will serve southern California style street food, but what's the big deal? I guess Johnson didn't want people to know his involvement just yet.

Oops. Johnson was hoping to keep that part a secret. His response is playfully sarcastic, suggesting that the 14 time most popular driver's tweet won't be seen by too many people.

After a closer look, however, we noticed that Johnson has Junior beat by 250 thousand followers on twitter. Subtle shade achieved!
