Mayor Bill de Blasio and First Lady Chirlane McCray are getting into spirit of the season, with the help of a few tiny friends.

The couple hosted a Halloween Spook-tacular at Gracie Mansion for hundreds of children yesterday, many from homeless shelters and foster homes from around the city

Kids decked out in all kinds of costumes got to tour the newly re-done "haunted mansion" and take part in face painting, magic shows and fortune telling.

Organizers also collected donations as part of the city's annual Halloween Food Drive.
