The very pregnant Kim Kardashian isn't going to let a little thing like a bun in the oven keep from hanging with her girls. The reality star got to have a girls' night out with tennis superstar, Serena Williams.

"I simply cannot get out of bed," Serena tweeted early yesterday (January 30th.)

"You better! We have dinner tonight!" Kimmy fired back.

They wound up going out and tweeting photos of the evening. "Fun girls night!!! But where's my nose Serena Williams? Lol. Too flashy," Kardashian joked, referencing a pic that obscured her nose.

"Such a fun night," Williams added. "Love you!"
