The former couple stood hand in hand as the Las Vegas crowd cheered for them. The cheers were even louder as they embraced on stage to finish off their live show, reported People magazine.
The duo has, for the most part, shown solidarity during "Q'Viva!", which began as a reality series in which the pair travelled the Latin world alongside executive producer and co-host Jamie King, searching for talent.
Lopez's evening, however, didn't end there as she headed to Hyde Nightclub following the show. Joined by boyfriend Casper Smart, Lopez danced on an elevated catwalk in a VIP area as the deejay played her songs.
Dressed in an off-white form fitting dress, Lopez finally left the club around 3 am after dancing the night away.
Anthony, who has twins Max and Emme with Lopez, filed for divorce in April this year to end their seven-year marriage.
