Speaking out: Jennifer gave a chat to People magazine about her new romance

Talking about his marriage he said on The Howard Stern Show: ‘We probably would’ve ended up at each other’s throats. I probably still would’ve been drinking.’

Ben went to rehab for alcoholism in 2018. He officially split with his ex-wife in June 2015, one day after their 10-year anniversary.

The couple co-parent three children: daughters Violet, 16, Seraphina, 13, and son Samuel, nine.

Elsewhere in the chat, Ben also admitted he thought twice about rekindling his J Lo romance due to the affect it could have on his children.

Ben told Howard: ‘It crossed my mind for sure. My responsibility to my children is the highest responsibility. I don’t want to do anything that is painful or destructive to them if I can help it.’

He added: ‘My life affects them. Me and their mom are celebrities. That is hard. That is a cross to bear,’ he told the radio host.
