Ananova:

Jennifer Lopez is said to have stunned the audience at a film premiere by kissing her boyfriend in the cinema.

J-Lo and actor Marc Anthony reportedly acted like a couple of teenagers in the back row on their first public date.

They kissed and cuddled while stars such as Denzel Washington, Queen Latifah and Christopher Walken looked on, says The Sun.

One onlooker in Los Angeles said: "People were looking at them as much as they were watching the film.

"The audience was quite surprised about how open they were being. There was no doubt that they are definitely a couple and she looked really happy. She was glowing."

The couple arrived separately at the premiere of the action movie Man On Fire in which Anthony, 33, stars with Denzel Washington as a kidnapped girl's father.

Father-of-three Anthony is divorcing his wife of five years.
