We were starting to think they were leading separate lives!

Kim and Kanye haven't been seen in public together too much in recent months, but that changed last night when they hit Chrissy Teigen's Pan-Am birthday party. The reality star looked gorgeous with her teased blonde 'do and retro peach dress, and her rapper hubby couldn't keep his eyes off of her!

The Sports Illustrated stunner and husband John Legend also looked the part in their outfits, and we've gotta hand it to the model for coming up with such an original theme for her bash! Party guests were supplied with fake cigarettes and Jackie-O magazine covers, and the whole thing took place on a fake airliner. How cool!

Kimmy K gave us a glimpse inside on her Snapchat, and we've gotta say, 'Ye isn't the best plus one! He might be happy on the inside, but he seems pretty bored and like he'd rather be at the studio making music!
