It looks like Emma Watson had a slight wardrobe malfunction while attending the London Premiere of her latest film "Noah."

According to Hollywood Life, while wearing the white Ralph Lauren Collection halter gown that featured a thigh-high slit that flaunted her tone legs, the 23-year-old showed a little more than she intended to.

While making her way through the premiere the thigh-high slit exposed the actress' spanks. Matt Janney's girlfriend wore a pair of shaping shorts that we are guessing were not meant for our eyes but hey, things happen.

Prior to attending the London premiere "The Bling Ring" star took to Twitter to post a photo of her essentials for a red carpet which included the spanks that hold the clever name "Commando."

Despite her undergarment wardrobe malfunction on March 31st Emma Watson looked gorgeous in all white and finished off her look with bold bright lips and a chic updo looking effortlessly glamorous.

The actress recently told Elle magazine that she tries to distant herself from her public life during her down time.

She explained to the magazine, "I don't date people who are famous, and I don't think it's fair that, all of a sudden, intimate details of their personal life are public as a direct result of me. I wish I could protect them."

Emma Watson gained fame portraying Hermonie Granger in the "Harry Potter" franchise and revealed that her time as a child actress at times makes it difficult to land more mature roles.

She confessed, "In my downtime I don't sex myself up much. Sometimes I have a hard time convincing directors that I can play more adult roles."
