The cast, contestants and further details for season 12 of Lifetime's Project Runway, which returns on July 18, were revealed Friday.

The model and Project Runway host celebrated with friends and family -- and an array of hats.

Designer Valerie Mayen is one of the three contestants from past seasons of the Lifetime series, Project Runway, who has a shot of being cast in Season 12 as a Runway Redemption contestant, which airs this summer. Mayen did not make it to the finale in season 8 of the show. The designer came in seventh but is up for a spot and another chance at winning the competition. Viewers will be able to vote for one of the three designers up for the coveted spot: Ra'mon-Lawrence Coleman from Season 6, Kate Pankoke who appeared in Season 11 and Mayen.

Heidi Klum was caught in the middle of an awkward protest.
