No entanglement is knotty enough to fell Will Smith and Jada Pinkett Smith. 

As they celebrate her 51st birthday Sept. 18, we offer the unbreakable pair the highest of fives.

Will Smith's response every time a new rumor forecasts the end of his marriage to Jada Pinkett Smith is a refrain.

"Divorce can't be an option. With Jada, I stood up in front of God and said, 'Til death do us part,'" he explained.

"So there are two possible outcomes. One, we are going to be together 'til death, or two, I am dead."

It's a sentiment his bride confirmed in a very honest 2018 episode of her popular Facebook Watch series, Red Table Talk.

 Ahead of their New Year's Eve vows, Jada, already two months along with their son Jaden Smith, now 24, was up front about her expectations.

 "I told Will from the gate, I said let me tell you something, 'If you marry me, know this: we're gonna be together.

 We're going to be under the same roof'... for me personally, I knew that there was no reason that he and I would ever [divorce]."
