Jennifer Lopez and Marc Anthony may be divorced, but they've still been able to attain a very professional relationship.

People reported the former couple will both be performing at Sunday's American Music Awards in Los Angeles.

The awards show will be their first public appearance together since July when they ended their seven year marriage.

And J.Lo's rumored beau, Casper Smart, will reportedly join her on stage as a dancer during her performance.

The 42-year-old will perform a three-song mash up of "Until It Beats No More", "Papi", and "On the Floor." She will also be doing a duet with Will.i.am. Anthony will perform his hit single "Rain Over Me" with Pitbull and Lil Jon.

According to Fox News, Lopez and Anthony will be seeing a lot more of each other after the awards show.

They two are currently still partners on an upcoming reality TV talent competition called Q VIVA The Chosen.

Very soon the worlds heart will beat to the tune of Latin rhythms and were looking forward to experiencing history in the making, Lopez said about the show.

It is with great pride that we embark on this amazing and very personal mission to discover and celebrate the most captivating talent the world has ever seen.
