Hilary Duff, Justin Theroux and Olivia Munn Lead Today’s Star Sightings

Celebuzz is ending the workweek with some of the biggest celebrity sightings from the past 24 hours.

In Hollywood, Hilary Duff was spotted all dolled up as she grabbed some grub at Aventine restaurant. The 25-year-old, who flashed a smile at photographers outside the eatery, rocked a mean shade of red lipstick for her outing.

On the east coast, Jennifer Aniston’s fiancé Justin Theroux braved the New York heat as he headed for lunch at Bar Pitti. The handsome actor kept things casual in an all black outfit and matching Supreme hat.

Elsewhere in the Big Apple, Olivia Munn enjoyed some girl time with Allison Williams, the always-fit Kelly Bensimon went for a jog while Cher headed to an interview ahead of this weekend’s Gay Pride festivities.
