Italia Ricci plays the part of a princess as she hosts Chagoury Couture‘s Fashion’s Night Out event in Los Angeles on Thursday (September 8).

The 24-year-old actress arrived in a chic black dress from the Ready To Wear collection before turning into a princess at the stroke of midnight — Italia donned a perfect pink tulle Chagoury gown for the party.

Earlier this week, Italia debuted the new poster for her upcoming movie, Valediction.

The movie’s official summary: Briefly stated, this film deals with life and loss. Whether it be loss of a person, ideal, or state in life. Things in life are constantly changing, nothing ever stays the same. We as humans are constantly bidding farewell whether we realize it or not.

Italia Ricci drapes herself in a gorgeous black gown as she steps out at the 2011 Diamonds Not Fur Gala held at Voyeur on August 27, 2011 in West Hollywood, Calif.

The 23-year-old actress was accompanied by boyfriend actor Robbie Amell to the gala which benefited SPCALA, the Society for the Prevention of Cruelty to Animals.

An uh oh, looks like the duo had to cancel their vacation to Cancun!

“So long Cancun trip…. @RobbieAmell has to keep booking and ruin EVERYTHING! ….fiiiiiine, congrats baby, I guess. (you owe me),” Italia tweeted.

Italia, 24, went for the gold on the orange carpet, wearing a Chagoury Couture dress with feather detailing.

Robbie stopped by to chat about his new pilot, Hallelujah, with JJJ on the carpet. He tells us, “I was a Lost freak and now I’m actually playing Terry O’Quinn‘s son on this new series. Terry‘s character still is kind of evil. My character is the cocky, arrogant son. He’s not the nicest guy, but he does drive a cool Corvette.”

Robbie Amell arrives at the Wilshire Ebell Theater in Los Angeles for the 24 Hour Hollywood Rush event early last week.

The 24 Hour Hollywood Rush benefited The Baby Dragon Fund which fuels programs at the Los Angeles Gay & Lesbian Center. Italia Ricci and Cassie Scerbo are also pictured.

JJJ ran into Robbie, 22, recently where he told us that he was eyeing a few roles in The Hunger Games film adaption.

While we can’t really see him as Peeta, we do think he’d be perfect for Gale Hawthorne, one of Katniss’ good friends whom she hunts with.

Robbie posted on his Twitter that he reads for Gale this week! Send him good luck wishes on Twitter @RobbieAmell!

JJJ recently caught up with the couple earlier this month and asked about their plans for Valentine’s Day.

Italia told us, “We were going to go away, but… I don’t know. Last year, I got him a magic bullet for Valentine’s Day. He uses it a lot for his protein shakes and everything. I’m not a romantic girly-girl. I don’t like flowers. The smell reminds me of funeral homes. That sounds so morbid (laughs). But he [Robbie] does get creative — bringing home all these weird flowers, the ones that don’t require direct sunlight.”

Robbie shared, “I have no clue what I’m doing. She doesn’t drop any hints at all. I will plan something but it’s pilot season so we can’t really go away. We would love to; I hear Hawaii is beautiful any time of year. If we weren’t in pilot season, I would so say ‘Let’s go to Hawaii for five days. Happy Valentine’s Day.’”
