Selena Gomez sobs at Spring Breakers premiere

Selena Gomez burst into tears after her new movie Spring Breakers was given a standing ovation at Italy's prestigious Venice Film Festival on Wednesday (05Sep12).

The actress walked the red carpet with castmates Vanessa Hudgens and Ashley Benson at the premiere of director Harmony Korine's gritty college caper, about a group of university roommates who rob a diner to fund a trip to Florida.

The 20-year-old former Disney star shed her squeaky-clean image to play one of the wild students, and admits she was overcome with emotion when the film won huge applause from the Venice crowd.

In a post on her Facebook.com page, she writes, "Tonight was one of the most amazing nights I've ever had. Our film got a standing ovation at the Venice film festival! I couldn't stop crying.

"Being a part of such an amazing project was such a blessing... I'm truly so blessed. I'm still in shock! I hope you guys enjoy Harmony's film making. He truly is amazing. Note: this movie is not for my littles (younger fans)... it's rated R! I just wanted to share this night with y'all! Love you!"
