Chrissy Teigen is one hot mom!

The 30-year-old model held hands with her husband, John Legend, leaving Khloe Kardashian's birthday party at Dave & Buster's in Los Angeles on Monday night, showing off lots of cleavage and leg in a silky button-up minidress. Chrissy paired the lingerie look with nude heels, looking glam for date night.

Other guests at Khloe's big bash celebrating her 32nd birthday were Ashlee Simpson and husband Evan Ross, singer Cassie, Scott Disick, her mother Kris Jenner's boyfriend, Corey Gamble, and of course, her famous siblings. Kim, Kourtney, and Rob Kardashian were all in attendance, as was Kylie Jenner and Rob's fiancee, Blac Chyna. Meanwhile, it appears Kendall Jenner was overseas for modeling work.

The family also made it clear there was no drama with Chyna, gamely posing for happy pics together.

Monday isn't the first time Chrissy has slayed since giving birth in April. Last week, she showed off her scene-stealing outfit at Electric Daisy Carnival in Las Vegas, again sporting an oversized dress shirt which she paired with skin-tight, over-the-knee boots.

ET chatted with Chrissy in May, when she talked about her diet since giving birth to her adorable baby girl, Luna.

"You just don't think about food as much," Chrissy explained. "So it's not that you're not hungry, or that you want to diet -- food just doesn't cross your mind. It's like whereas before it was number one on my list, now Luna's up there, and John and keeping the dogs happy, because they get jealous. And then you're like, 'Oh, I haven't eaten in seven hours, this is horrible.'"

She also isn't worried about following a strict exercise routine.

"I still have a couple more weeks before I can work out -- which is fine with me," she admitted. "I love the feeling of working out, but I've never been a gym rat, ever, so now, it's all about taking in what I can if it's good for the baby, because it all translates to her in a way."
