Marc Anthony and Jennifer Lopez ''live crazy lives'' but always make time for their children.

Marc - is father to 18-year-old Arianna from a relationship with Debbie Rosado, 12-year-old Cristian and nine-year-old Ryan with his first wife Dayanara Torres, and twins Emme and Max, five, with J.Lo - is trying to balance work with his children and praised his former partners for making an ''effort'' to make sure he has family time.

He told the new UK issue of HELLO! magazine: ''We live crazy lives, but we have always made it clear that we need to be present and involved in their lives and to make an effort.''

Marc - who was spotted with Jennifer, who he split from in 2011, and the twins at a school event in Los Angeles last month - revealed J.Lo works with him to ensure their schedules work for the kids.

He added: ''We compare our timetables and modify them to make sure we can have this time.''

Despite having a colourful love life, the singer/songwriter - who recently rekindled his romance with 22-year-old Topshop heiress Chloe Green - is happy in his personal life and is thankful for everything that he has been blessed with.

Marc - who was married to J.Lo for seven years - said: ''I'm happy and very fortunate. I have lots to thank God for.''
