We're guessing Yeezy looooved this outfit!

On Tuesday Kim Kardashian squeezed her pregnant belly into yet another skintight dress, and she stopped by the Hollywood studio where hubby Kanye West was working on new music. Kanye didn't emerge from the building for another couple of hours, and when he did he was joined by an assistant -- and he wasn't exactly in the best mood. Yikes! Was it something Kim said or is he just stressed with work?

Over a year ago producer Rick Rubin confirmed that he was working on Kanye's new album, and though it seemed to be on pause for several months, Yeezy's been back at it lately and spending a lot of time at the studio. Perhaps that's causing problems with Kim, especially since she's preggers with their second child? Last month Kanye phoned in to Hot 97's morning radio show to chat about the progress he's making and he said, "[I'm working] on it slowly, make it an art project, you know, deliver the innovation that I know I have consistently done since 808s and Dark Fantasy." Seems like he's back in work mode now!

Late last year this was a major problem, and Kanye's desire to spend more time working than with his family caused some major drama. "When they got married the deal was they would spend time together with the baby," a source told the Mirror at the time. "But he hasn’t kept up that promise. He’s super busy and continuing his crazy schedule. Right now for the holidays especially, it was all supposed to be resolved, but it’s still causing a major problem."

Maybe Kim just wants to make sure things don't get out of hand again? As you may remember, Yeezy totally ditched her on Thanksgiving!
