Bethenny Frankel has launched a foul-mouthed rant defending Tom Brady and Alix Earle's rumoured age-gap relationship

Bethenny - who has her own dating service, The Core - said in an Instagram video: "Let me ask you something about Tom Brady and Alix Earle. And it's not, 'Why does anyone care?' Because everyone cares.

"Why aren't they allowed to do what they want to do?

So, they're two consenting adults.

"He is a legendary, disciplined athlete that is respected by his entire community and everyone he's worked with, and Alix Earle is a successful influencer who is showing up on time and seems to have good, meaningful friendships.

"Let's say that they hung out for five minutes, zero minutes, or they, in five years, decide to spend the rest of their lives together. Why shouldn't people do what they want to do?'

"Now, dating with my membership community, we don't set people up that are 25 years difference because we don't believe that it's setting people up for alignment, and we want people who want to meet their life partner right now.

"Doesn't mean there aren't exceptions, there are many exceptions.'

"This particular case, these two people are legal, consenting adults, they come from good families, he raises good children, and everybody's not gonna get every score perfect on every choice either.

"And by the way, life is short."

The 55-year-old TV personality insisted "life is short" and people should "do what you want to do" rather than worry about what others think.

She added: "I can promise you that when they're closing the box, if that's how you decide to go, you're not going to be saying, 'I wish I did more of what everybody wanted me to do,' or wore more of what everybody wanted me to wear, or said more of what everyone wanted me to say. F*** it.

"Life is short. Do what you want to do, live how you want to live, live with integrity and ethics, try to do the best you can and be good, and you won't always even be that, and everyone can f*** off."
