Big Sean and Ariana were just spotted together Wednesday, just a day after she took the stag at the Victoria's Secret Fashion Show Tuesday. Ariana held tight to a black and white Victoria's Secret as she strolled through Los Angeles International Airport. Her full outfit was not seen as the blanket covered up most of it and played coy with cameras, but pictures reveal she rocked a midriff top with short flat, black boots and tights. Big Sean was not too far behind. He stepped out in a casual outfit as well.

It was complete with a grey t-shirt under a white hoodie and black leather bomber jacket. He also wore a pair of fitted jeans with black boots.

Check out the pictures here.

Ariana took to her Twitter to thank cameramen at the airport for being polite to her.

"thanks to the paps at the airport for being nice, not terrifying, safe & sweet this am. even tho I was sleepwalking lmao. I appreciate itttt".

She also shared a picture of a bouquet of flowers on Instagram Saturday that are possibly from the Clique rapper.
