One perk of being married to John Legend: getting serenaded on your birthday.

Chrissy Teigen, who turns 30 on Monday (Nov. 30), celebrated early with a party at Comedy Cellar in New York City on Saturday night (Nov. 28). Legend sang to her, and the pregnant supermodel and co-host of Lip Sync Battle was also treated to a surprise performance by Dave Chappelle, Popsugar reports.
