Marc Anthony's got a new special someone in his life -- and she's already bonded with his kids at the Happiest Place on Earth! On Tuesday, the Latin crooner, 44, treated 5-year-old twins Max and Emme to a day at Disneyland in Anaheim, Calif. For the romp through the Magical Kingdom, Jennifer Lopez's ex also brought along Chloe Green, the 21-year-old British heiress to the Topshop fortune and former reality star (British show Made in Chelsea).

By all appearances, Anthony and Green are a romantic item: Throughout the day at Disneyland, they held hands and kept their arms around each other. Green (her father, Sir Phillip Green, owns the fashion store chain Topshop) was also photographed bonding with the twins, with Emme sitting on her lap for one kiddie-sized ride. (The day may have been a makeup birthday treat for Max and Emme, who turned 5 Feb. 22, with Lopez whipping up a batch of homemade cupcakes in their honor.)

Max and Emme, of course, have grown used to hanging with their parents' significant others: Their world-famous mom Lopez, 44, has been dating Casper Smart, 25, for well over a year, and have spent plenty of quality time with the hunky dancer-choreographer.

Anthony -- he and Lopez announced their split in July 2011, but have yet to finalize their divorce -- split from model Shannon De Lima back in January. That split appeared to be amicable enough for De Lima to join Anthony, Lopez and Smart for a sweet birthday party in honor of Cristian, Anthony's 12-year-old son from a previous marriage.
