AceShowbiz - Addison Rae may be stressing over something in a new sighting. The actress portraying Padgett Sawyer in "He's All That" did not appear to be in good spirits in a new sighting as her latest single flopped.

On Tuesday, September 3, the 23-year-old actress/singer, who rose to fame on TikTok with over 88 million followers, was out and about in Los Angeles, California. In a series of pictures that made their rounds online, it could be seen that she was walking alone.

Addison was caught on camera apparently making her way to a parking lot. At one point, she was photographed opening the door of her luxury black car. She was carrying a chess board in her hand and placed her smartphone on it.

Throughout the outing on the sunny day, Addison seemingly was not in a good mood. She was pictured looking straight at a paparazzo's camera while showing a serious facial expression without a smile on her face.

For the relaxing solo stroll, Addison went with a revealing vibrant outfit. She showed off her stomach in a white crop top that came with black stripes all over it. The clothing piece also featured two straps and a knot on the wearer's bodice.

The TikTok star completed the look with a pair of long pink sweatpants, which had a wide leg and low waist design. The pants were long enough to nearly cover a pair of light-colored flat shoes, which made her look as if she was only wearing a pair of socks.

Addison accessorized herself with a gold necklace that came with a big pendant on its end, a pair of sunglasses and a small blue shoulder bag. In addition, she styled her long hair in an updo and parted it in the middle.

Addison looked somber seemingly because her latest single "Diet Pepsi" has yet to crack the Billboard Hot 100 singles chart. The song, which was her major label debut single, was released through Columbia Records on August 9.
