Jennifer Lopez has given Marc Anthony's new relationship her blessing.

The 'On the Floor' hitmaker has remained close to her ex-husband since they split in July 2011 and she got on well with Topshop heiress Chloe Green when she met up with Marc and her to discuss their children, five-year-old twins Max and Emme.

A source told the new UK issue of Grazia magazine: ''Jennifer invited Chloe and Marc over to discuss the kids and the two women bonded.

''She and Marc are still close. She wants him to be happy.''

Chloe - the daughter Sir Philip Green is said to be so serious about her romance with Marc, 44, that she is considering a permanent move to America to be with him.

A source close to the 22-year-old designer said: ''Chloe and Marc have totally fallen for one another. She's been looking into getting a place in New York, where they love to hang out, or Miami, where his family are based.''

Jennifer, 43, is in a relationship with dancer Casper Smart, who, at 25, is 18 years younger than his superstar girlfriend.
