Only 20 close friends and family attended their Barbados weeding.

• Mark Cuban met his wife, advertising executive Tiffany, at the gym in 1997.

• Earlier in their relationship, Tiffany had trouble adjusting to the billionaire's lifestyle and the couple experienced "scheduling problems."

• They were wed in an intimate 2002 ceremony in Barbados, and now have three children.

"Shark Tank" star and Dallas Mavericks owner Mark Cuban has long teased a run for the White House.

As an outspoken critic of US President Donald Trump, Cuban even weighed the possibility of taking over the Republican ticket at some point.

But if Cuban's wife Tiffany Cuban has anything to say about it, a run for the White House may be off the table. CNBC reported that he said he would be far more tempted to toss his hat into the political ring if he was single.

The couple wed in 2002, and is currently worth $3.3 billion, according to Forbes.
