Speculation over just what caused the fight has been rife; had he cheated on Beyoncé, was Solange angry that he didn't give her album more promotion, was she drunk?
The couple shed some light on what happened with their statement, however some are suggesting it may have all been an elaborate plan to get her name in the press.
According to HipHopDX, the singer's sales were at 2,000 the week the news broke, compared to 600 the week before.
Although we'd hardly call these Beyonce levels - remember when she broke iTunes! - it proves the old adage, all publicity is good publicity.
With the three of them all heading for lunch together just a week after the incident it seems perhaps they are still a very happy family.
