"A special man" ... Amber Heard gushes about reported new boyfriend Johnny Depp.

Amber Heard says Johnny Depp "lights up a room".

The American actress has been linked to the Hollywood star following the end of his 14-year relationship with Vanessa Paradis.

Heard and Depp become close after they shot the 2011 movie The Rum Diary together and she has visited him on the set of his new movie The Lone Ranger in New Mexico.

The actress has gushed about Depp, according to British newspaper The Sun.

"He lights up a room," she is quoted as saying. "He looks even better close up. Johnny is a wonderful, special person."

Heard starred as Depp's character's love interest in The Rum Diary, and it was when she was promoting the movie that she revealed he chose her for the role.

The pair haven't commented on their relationship status but they have been spending increasing amounts of time together. They were spotted together in Las Vegas earlier this year and this week there were reports Depp, 49, has splashed out on a horse for the 26-year-old star.

Heard, who is open about being bisexual, was dating a female photographer in 2010.

"I love men. I go where my heart takes me. I'm like any girl - a sucker for romance," she has said.
