The superstar took a break from her own singing duties to support Jay-Z in his joint 'Legends Of Summer' tour with Justin Timberlake on Sunday (28 July).
While backstage at the Rose Bowl in Pasadena, California, Queen B snuggled up to Fantastic Four actress Jessica and her model friend Kelly Sawyer.
Beyoncé, who wore an oversized striped top and a slick of red lipstick, was all smiles as she chilled backstage.
The 31-year-old, who suffered a hair mishap with a fan last week, certainly looked like she's close friends with Jessica as she rested her head on her shoulder.
Jessica, 32, also beamed in a stripe top and green leather jacket, as she watched the powerhouse duo deliver their hits to a 60,000-strong crowd.
Beyoncé, who is currently on the north American leg of her mammoth 'Mrs. Carter Show' world tour, wasn't the only star in attendance. Jessica's husband Cash Warren was also present along with Jesse Metcalfe and his fiancée Cara Santana, and Beyoncé's Destiny's Child band mate Kelly Rowland.
