Jennifer Lopez and boyfriend Casper Smart looked as though they were ready for some late night loving yesterday when they were spotted being affectionate with one another on the balcony of their hotel in Rio de Janeiro, Brazil.

The couple had spent the weekend enjoying the festivities of the Rio carnival and spent most of the day in their VIP box. They then spent the evening alone in their hotel and put on a display of public affection on their balcony, with Casper stroking Jennifer's neck and kissing her on the forehead.

Jennifer is said to be on the verge of having a meltdown following a stressful year, which saw her split from her husband of seven years Marc Anthony and then jump straight into a whirlwind romance with 24-year-old dancer Casper.

Check out the pics of the PDA moment in the gallery below.
