Why party like it’s 1999 when you can party like you’re single? It seems this is exactly what Marc Anthony was doing in Costa Rica, since going through the motions of divorce from wife Jennifer Lopez.

TMZ reports that while in Costa Rica to promote the launch of his new Latin singing competition show, ¡Q’Viva! The Chosen, Anthony threw a big party.

He was having so much fun, the 43-year-old jumped behind the DJ booth and played a few cuts for the crowd and was also seen being kissed by and cozying up to a dark-haired woman, who is said to be a part of the production team.

Although they’re no longer an item, ¡Q’Viva! is a joint project with J.Lo and will be shown in English, Spanish and Portuguese.
