Chrissy Teigen poses TOPLESS while snuggling in bed with her dog in new photo... and reveals she lost her mind at reunited NSYNC concert during whirlwind week

Chrissy Teigen unveiled a risqué photo of herself when she shared an update on her busy week on Tuesday.

The 38-year-old model posed topless in one photo that showed her wrapped up under her thick covers in bed.

Despite her racy appearance, Chrissy — who was recently seen helping her daughter Luna sell Girl Scout cookies — seemed to be having a sweet moment with her French Bulldog Penny.

Chrissy's week in review also recounted when she got to see Justin Timberlake and the rest of the reunited NSYNC lineup performing on stage.

'week in review!! Sports, food, *NSYNC, jello for papa and we have a temporary new bird!' she gushed in her caption.

Chrissy included a clip from seeing NSYNC perform in which Justin Timberlake shouted, 'Let's turn it up!' which got the crowed cheering even louder

Chrissy's semi-nude moment in bed may have been as she recovered post-concert, as she had a lime green band on her wrist as she snuggled with Penny.

Penny is Chrissy and her husband John Legend's oldest dog.

The singer revealed on The Voice in February that the adorable black-and-white pooch was 'born the week Chrissy and I got married.'

He shared that the lovebirds adopted the dog from a shelter in South Carolina while he was on his All Of Me Tour.

'She’s our oldest and most loving dog,' John said.

Penny is also notable as she has only three legs, though that hasn't stopped her from being an active member of their family. 

They also have two other cut dogs, Petey the Poodle and Pearl the Basset Hound.

Chrissy included a clip from seeing NSYNC perform in which Justin Timberlake shouted, 'Let's turn it up!' which got the crowed cheering even louder.

As the music heated up and he and his fellow singers started to bounce to the beat, the Sports Illustrated Swimsuit Issue model turned her camera around to show her face in closeup as she cheered along.

Another closeup video featured the couple's second-youngest child, one-year-old Esti, who was born on January 13, 203

Her face, hands and high chair tray were all covered in red juice, which appeared to be from a pacifier Chrissy handed her with cold fruit puree in the tip, possible to sooth teething pain

Chrissy's oldest children, Luna, seven, and Miles, five, popped up in multiple snaps, including a silly one in which they sat on the granite counter top while eating from a plate of green jello

The two looked cute in a another photo of them cooling down with red, white and blue popsicles

Another video featured Chrissy's five-year-old son Miles, who had written a note for the family's new parrot, who was located in a cage near the kitchen.

'What does it say, Miles?' Chrissy asked to prompt her son to read the notes.

'Audrey, do you like our family?' he read, before she turned the camera to reveal an array of sticky notes on the cage that asked if Audrey liked 'soccer' and 'basketball.'

The cute bird was mostly green, with some red around the base of her wings and white patches connecting her eyes and beak, suggesting that the family might have bought a Red Shouldered Macaw.

Her face, hands and high chair tray were all covered in red juice, which appeared to be from a pacifier Chrissy handed her with cold fruit puree in the tip, possible to sooth teething pain.

Esti was more interested in playing around than relaxing, and she flung the pacifier on the ground as soon as Chrissy handed it to her.

Chrissy's oldest children, seven-year-old Luna and Miles, also popped up in multiple snaps, including a silly one in which they sat on the granite counter top while eating from a plate of green jello.

Chrissy highlighted Miles' athletic prowess with a short clip of him getting coached at one of his baseball games

It wasn't all fun and games for the social media star, who revealed that she had dozens of copies of her latest cookbook Cravings: All Together that required her signature

But she got to enjoy some of her tasty treats in another short video in the post. She was seen with her delicate long claws as she stirred a jar of her Cravings-branded chili crisp, which was spiced up with a 'smoky chipotle' flavor
