Teigen, who covered her baby bump in a short, silk navy wrap dress, and Legend were presented with a number of pastel blue and white cakes from Hansen's Cakes, which contained phrases such as "Legend in the making", "You're a legend" and "Legendary".
Kardashian West captured her tucking into the cake while sitting on the kitchen counter. In the clip, the 37-year-old reality star says: "Chrissy ate that entire cake herself, you guys". Other notable guests at the event were Jesse Tyler Ferguson, and Kanye West, who had disagreed with Legend on Twitter earlier in the week over his pro-Donald Trump tweets.
However, there is no bad blood after the two's heated exchange as they both were seen dancing together at the after party. Kanye also shared a video of the entertainer playing his song Ordinary People on a slick wooden piano at the party, writing: "Lead With Love".
