Celeb Spotter 105: Margot Robbie, Dakota Johnson, 'Queer Eye' cast and more celebrity sightings

The "Once Upon A Time... In Hollywood" cast continued to dominate the conversation this week, stepping out for a variety of high-profile appearances, including the British and German premieres of the Quentin Tarantino film.

As per usual, Margot Robbie was the star of the red carpet, rocking a series of memorable ensembles for the events -- while Lena Dunham turned heads in a feathery look as she planted a kiss on co-star Brad Pitt.

Also out for big premieres this week were Amanda Seyfriend, Milo Ventimiglia and Patrick Dempsey, who attended "The Art of Racing In The Rain" premiere in Los Angeles, where producer Dempsey brought along the rest of his gorgeous family for a rare outing together.

More of our favorite sightings this week came from the cast of "Queer Eye," Renee Zellweger, Dakota Johnson, Angela Bassett and more.
