Although Stewart and Maxwell haven't confirmed their relationship, the duo have been spending a lot of time together in recent months
The Twilight star, 26, attended Tommy Hilfiger’s second annual TOMMYLAND show in Venice Beach, California, in support of Maxwell.
While the 26-year-old Victoria’s Secret Angel strutted down the runway in a preppy collared crop top paired with striped blue pants, Stewart watched from the crowd donning a more grunge-inspired look. She paired black jeans with a black hoodie, topping it off with a black beanie.
The duo were also photographed together before the event, talking and smiling as Maxwell crouched against a wall.
Stewart wasn’t the only famous face in attendance. Lady Gaga showed her support for the fashion brand, and Yolanda Hadid also came to applaud daughters Gigi and Bella Hadid with the rest of the family.
Although Stewart and Maxwell haven’t publicly addressed their relationship, the duo have been spending a lot of time together in recent months.
The pair were recently spotted spending time together in Savannah, Georgia, where Stewart has been filming a new movie about Lizzie Borden, and just last month they enjoyed a fun night out at Knott’s Berry Farm theme park in Buena Park, California.
