Sofia Richie was ready to take flight in her flightsuit jumper! The 21-year-old girlfriend of Scott Disick took a break from the Kardashian clan just long enough to pop over to Italy for the Venice Film Festival but she didn't stay a moment longer than she had to!

Richie's visit to The Floating City was a bit of a mystery to begin with -- she's not an actress, she has nothing to do with any of the films at the festival, but she looks good on the red carpet?? It seems she appeared as a vehicle for product placement -- the vintage Christian Dior bikini, the Please Don't Buy signed by Twinset crop-top/skirt on the red carpet that she paired with Andrew Wazen heels. See! The "organic" PR worked!

Richie couldn't get back to boyfriend Disick fast enough -- and certainly she was nervous she'd miss a big Kardashian event that she'd forever regret. Sofia slid into Jordyn Woods' spot as Kylie Jenner's BFF and that's a relationship that needs nurturing, so you can't let it go for too long. Now Sofia can get back to sleep overs with her girls, private-jet trips to Vegas, and focusing on cultivating her Instagram account with photos that reveal her latest plastic surgery. Hey, that's what "keeping up" is all about!
