Chloe Green, the daughter of Topshop founder Sir Phillip Green, looked less glammed up than usual following reports that she and boyfriend Marc Anthony split.

The couple recently started dating but have already gone their separate ways. Green is even said to have moved to the U.S. to be closer to the 44-year-old singer.

"The pair got serious very quickly and had the blessing of her parents, but it hasn't worked out," a source told the Sun on Sunday. "It seems to have been Marc's decision to end it."

A spokesperson for Green confirmed to the Daily Mail that they are not together anymore.

Anthony only recently announced a split from his previous girlfriend, model Shannon De Lima, at the end of January, but he and Green looked quite comfortable together just earlier this month, as they held hands while Green embraced him during a trip in Miami.

In February, the Latin sensation even brought the 21-year-old along to Disneyland with his 5-year-old twins (with Lopez), Max and Emme. Anthony was married to Jennifer Lopez for 8 years.

Us Weekly reports that Green’s father was also in attendance. Philip has been involved with British Home Stores, Topshop and the Arcadia Group. He is worth roughly 3.3 billion pounds ($5 billion), according to the Daily Telegraph.

Despite the age difference, Philip seemed to approve of his daughter’s relationship.

The New York Post reports they all went out on the town in Miami alongside Chloe’s mother and brother to club Set.  Sources told the newspaper that the British heiress’ parents looked on in approval and that they looked “like a happy couple.”

Though Green and Anthony split, Lopez, 43, is still going strong with boy toy Casper Smart, who is 18 years younger than her.
