Sometimes a girl needs her Spanx! Kim Kardashian had a slight wardrobe malfunction while at the opera in Rome on Sunday night.

The 35-year-old reality star stepped out in a stunning one-shoulder white gown by Vivienne Westwood while at the glamorous event with her hubby, Kanye West. She Snapchatted several videos and photos from the swanky affair, sharing them with her many followers.

While recording something, presumably a Snapchat, on her phone, the thigh-high slit in her gown (which she had been carefully monitoring all night), flew open slightly, exposing her Spanx.

It’s not like the gorgeous mother of two even needs the body shapewear. Earlier this month she revealed that she’s back to her pre-baby weight after giving birth to son, Saint West, last December thanks to the Atkins diet.

“I gained 60lbs during my pregnancy but have been an extra 10 lbs up for the last few years so it's time to really get to my goal,” she tweeted in January.

While Kim was off in Europe, her sisters Khloe and Kourtney Kardashian were having a blast in Las Vegas, attending Jennifer Lopez’s Las Vegas residency show. Khloe posted a fun group shot with her sister, J.Lo, Meghan Trainor, Laverne Cox, and Jessica Alba.
