Mariah Carey Teases John Legend on Stage, Chrissy Teigen Completely Loses It

Chrissy Teigen and John Legend hit up Mariah Carey's Las Vegas concert on Saturday night, and judging by these photos, they had a whole lot of fun. During Mariah's performance of "Touch My Body," John joined the singer on stage by jumping onto a bed, where one of her dancers quickly blindfolded him. Moments later, Mariah proceeded to tease the new dad by rubbing a giant pink feather on his neck. But that wasn't the best part!

Chrissy was front and center in the audience having a total fangirl moment, screaming, dancing, and cheering on her husband. She later took to Instagram and wrote, "Mariah pulled @johnlegend on stage at her Vegas show and as a lamb, I have never been so happy. There is no Mariah song I don't know the words to and I may have cried but whatever I LOVE YOU @MARIAHCAREY thank you for this amazing night for me and my family!!" That same evening, John posted a photo of him, Chrissy, and Mariah, captioning it, "We go back like babies and pacifiers."
