Watch John Legend serenade Chrissy Teigen to celebrate her 30th birthday

Happy 30th birthday to 2014 SI Swimsuit cover model and hot mama-to-be, Chrissy Teigen! 

Chrissy's husband, John Legend, hosted an intimate, early birthday celebration on Saturday night with family and friends at the Comedy Cellar in NYC, and the expectant parents could not look more precious as they rang in Chrissy's 30th year of life. 

Among attendees were Chrissy's friend Simon Huck, celebrity publicist, and Dave Chappelle, surprise guest and entertainer for the night. But perhaps the most important (read: awwwww-inspiring) moment of the night came when John took to the stage to sing "Happy Birthday" to his love (read: SEXY baby mama).  

We've written countless times about just how damn cute these two are, and Chrissy's birthday celebration only further ensures they will forever set the bar for our #RelationshipGoals. Happy birthday, Chrissy; may your 30s treat you as well, and even better, than your 20s did!
