"She looks like Shannon," one fan wrote in Spanish, while another added, "Living the vida loca," obviously confusing Ricky Martin's famous lyrics with Marc's.

After announcing his divorce from his fourth wife last year, sources revealed exclusively to Life & Style that the father-of-five was determined to win back Jennifer Lopez. However, the "Ain't Your Mama" singer wanted to protect her eight-year-old twins, Max and Emme.

"She was having major doubts because of the trust issues she’s always had with Marc,” the source said. "[She] didn’t want to put the kids through the emotional turmoil of possibly getting back together with their dad if it wasn’t on solid ground.”

It looks like Marc is coping just fine. For more of Mariana's hottest Instagram moments, click through the gallery below!
