But for once the pair, and their gorgeous red carpet PDA, were outshone: by none other than Chrissy's sparkly baby bump.
The couple, who have been open about their struggles to conceive naturally, announced they were expecting their second child together in November of last year through IVF - the same process that they used to conceive their daughter, Luna.
After leaving the Grammys early, Teigen posted an Instagram confirming that the sex of her second baby is a boy.
"Mama and her baby boy," the glowing model captioned the photo.
Teigen has also been refreshingly honest about the postpartum depression she suffered following the birth of Luna, who turns two in April.
In an open letter to Glamour, Teigen wrote: "I couldn’t figure out why I was so unhappy. I blamed it on being tired and possibly growing out of the role: “Maybe I’m just not a goofy person anymore. Maybe I’m just supposed to be a mum."
Speaking to marie claire, the 31-year-old said she is scared of having PPD again but is thankful she now knows coping mechanisms and has the support of her husband and family.
“It couldn’t be any worse than it was, could it? Every step I take feels a little shaky. It’s such a weird feeling that you wouldn’t know unless you have really bad anxiety… You feel like everyone is looking at you.”
