It's tricky to spot stars who are unrecognizable in public!
That was the case this week with Tara Reid, who stepped out in LA looking nothing like the sweet-faced "American Pie" star we all know. It's no secret she's been through a lot since her heydey, but in this platinum-blonde wig and super-heavy makeup, would you even know who she is?
On the other end of the fashion spectrum, Heidi Klum put her best foot forward in New York in comfy white sneakers, which she paired with a relaxed tee-and-jeans combo. Must be a nice break from the stilettos she normally rocks!
Other notable spottings: Jaden Smith donned an eye-catching ensemble on the streets of Soho, Hoda Kotb was all smiles in a patterned halter dress, and Lori Loughlin hid from the paparazzi in a big hat and dark shades.
