Jennifer Lopez praises her husband's parenting skills

Despite the fact he appears to be a vampire, Jennifer insists that Marc is brilliant with their children, even getting up in the middle of the night to look after the pair, though surely he's up anyway - that's when his powers are at their strongest?

"I can ask him to get up in the middle of the night if one of the kids wakes up. Every single time he's say OK. That's a huge thing. If you have a partner who doesn't think it's their job... then that's really hard."

A lesson to all new fathers out there. It's the little things like this that make all the difference, like saying 'Leave this one to me' when the babies start to cry in the night, and then pressing the buzzer for one of your team of nannies to sort the little bleeders out, while you roll over and start to snore, or turn into smoke and drift out of the window looking for fresh blood.
