Speaking on US talk show Today at the beginning of August, Alex said of the pair: ‘To be honest if this happened when we were in our twenties… it would have never happened.

‘It was just too much craziness, I wasn’t mature enough,’ he explained. ‘You know boys…. we gotta get our dumbness out of the way.’

‘We’re both in our 40s, we’re both from New York, we both come from Latino backgrounds, we both have two kids,’ he added. ‘I think we’ve both been through a lot and can really appreciate each other… both the good and the challenges.’

She chose to ignore the rumour-inducing jewellery and simply captioned her shot: ‘It’s the lil quiet moments that matter the most…’

The insider added: ‘They’ve been combining their finances. They are very happy and have a great relationship. They’re committed to each other and their families, and that’s what matters most.’
