The three US X Factor judges showed plenty of girl power as they posed for photos at the FOX Summer TCA All Star Party.
Demi, 20, looked chic in all-black as she rocked skin-tight leather pants, a black blazer with leather sleeves and peep-toe heels. Demi vamped up her look with black nail polish on her fingers and kept the fringe of her glossy blonde hair swept to one side.
Meanwhile Kelly flashed her long legs in a white and blue minidress. Demi and Kelly already showed off their close bond earlier this week, as they watched Jay-Z and Justin Timberlake perform in concert, and things were no different last night, as they shared a giggle in front of photographers.
Fellow judge Simon, 53, was absent from the photocall but he did join them later for a press conference where he addressed recent baby rumours.
Demi also appeared to be close to Mexican singer Paulina, who joined as a new judge for this season.
The 42-year-old flaunted her tanned pins in a white mini dress and skyscraper heels, and was seen sharing several cuddles with Demi. Paulina later took to Twitter and called Demi her "little sister".
Camp Rock actress Demi, who is enjoying her second year on the talent show, has also been gushing about her new BFFs. She tweeted last night: "LOVE the people I'm working with... I'm SO beyond blessed."
