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 revealed a risqué photo of herself on Tuesday as she shared an update on her busy week.

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

Despite her feisty appearance, Chrissy — who recently helped her daughter Luna sell Girl Scout cookies — seemed to be having a fun moment with her French Bulldog Penny.

Chrissy’s weekly recap also detailed when she saw Justin Timberlake and the rest of the reunited NSYNC lineup perform on stage.

‘weekly overview!! Exercise, food, *NSYNC, jello for dad and we temporarily have a new bird!’ she gushed in her caption.

Chrissy’s semi-nude moment in bed may have been while she was recovering after the concert, as she had a lime green band on her wrist as she snuggled with Penny.

Penny is the oldest dog of Chrissy and her husband John Legend.

The singer revealed on The Voice in February that the adorable black and white dog was “born the week Chrissy and I got married.”

He said 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 also stands out because she only has three legs, but that doesn’t stop 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 added a clip from watching NSYNC, with Justin Timberlake shouting, “Let’s turn it up!” making the crowing cheers even louder.

As the music heated up and he and his fellow singers began bouncing to the beat, the Sports Illustrated Swimsuit Issue model turned her camera to show a close-up of her face as she cheered along.

Another video showed Chrissy’s five-year-old son Miles writing a note for the family’s new parrot, which was in a cage near the kitchen.

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

“Audrey, do you like our family?” he read, before turning the camera to reveal a series of sticky notes on the cage asking if Audrey liked “football” and “basketball.”

The adorable bird was mostly green, with some red around the base of her wings and white spots connecting her eyes and beak, suggesting the family may have acquired a red-shouldered macaw.

Another close-up video showed the couple’s second-youngest child, one-year-old Esti, who was born on January 13, 203.

Her face, hands and the 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, possibly to ease the pain of teething.

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

Chrissy’s oldest children, seven-year-old Luna and Miles, also popped up in several photos, including a silly one where they sat on the granite counter while eating from a plate of green jello.

The two looked adorable in another photo where they cooled down with red, white and blue popsicles.

Chrissy highlighted Miles’ athletic prowess with a short video of him being coached during one of his baseball games.

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

But in another short video in the post, she was able to enjoy some of her tasty treats.

She was seen using her delicate long claws as she stirred a jar of her Cravings brand chilli chips, which were flavored with a ‘smoky chipotle’ flavour.
