Chrissy Teigen Looked Sexy in Dressing Room of A Mystery Christmas Project in Loas Angeles Wearing Clad Bra!

Lip Sync Battle’s Chrissy Teigen flashed her underboob while clad in a bra and Spanx in the dressing room of a mystery Christmas project in Los Angeles on Sunday.

‘This is pure moisture,’ the 32-year-old wisecracking presenter – who boasts 30.6M Twitter/Instagram followers – said over Insta-story.

‘We’re pretending it’s Christmas and it’s so hot out. This is sweat, look at my bra.’

Make-up artist Patrick Ta applied the Hotel Transylvania 3 actress’ fully-contoured complexion and red pout while hairstylist Glen Coco coiffed her natural bob for the shoot.

Chrissy was most likely on the set of a music video promoting her husband John Legend’s forthcoming, debut Christmas album.
