Since splitting from Jennifer Lopez in July, there's no doubt Marc Anthony is missing seeing their twins Max and Emme every day.
So the singer could be forgiven for being unhappy by the latest photographs of his estranged wife with her new toyboy boyfriend Casper Smart, seen bonding with their children.
Dancer Smart, 24, joined Lopez, 42, on a family holiday to Kauai, Hawaii for Thanksgiving last weekend along with her mother Guadalupe.

Curly-haired Emme looked like she was in fits of giggles as Smart held her upside down as they frolicked by the sea.
An eyewitness told Us Weekly: 'Casper was great with the kids. Casper twirled Emme and Max around in the water. The twins played tag and chased Casper.'
After their six-day Hawaii break, it is thought the twins are now in the U.S. with their father while Smart accompanies Lopez on a work trip to Morocco after she was photographed arriving in the North African country via private jet yesterday.
