JUSTIN Timberlake has reportedly been cheating on Jessica Biel.
The singer apparently kissed married Brazilian actress Thaila Ayala while in Rio de Janeiro for the Rock in Rio Festival in mid-September.
“Jessica flipped out… she’s afraid that Justin is incapable of controlling his impulses,” a source said.
“Jess is really worried. She wants to believe that he’ll be faithful, but it’s hard to tune out all the chatter suggesting otherwise.”
