Emily Ratajkowski, Ashley Tisdale and Kirsten Dunst lead the stars taking their children out in spooky costumes on Halloween

Emily Ratajkowski, Ashley Tisdale and Kirsten Dunst were among the famous faces knocking door to door for candy and treating their neighbors to sweet treats as they celebrated Halloween Tuesday night.

While trick-or-treating with their families in the United States, the stars seemed thrilled to spend quality time with their little ones, who were all dressed in adorable costumes, from Ursula the Little Mermaid to Curious George.

For her daughter Jupiter’s third Halloween, Tisdale, 38, transformed into Professor Marie Katherine Wiseman from TV series Curious George, while her husband Christopher French dressed up as George’s father, Teddy Shackleford, also known as Man in the Yellow Hat.

Their little girl looked absolutely adorable in a monkey costume with a red T-shirt that read: ‘Curious George.’

The trio was spotted embracing the holiday spirit by capturing the essence of the classic children’s story in their well-coordinated costumes while in Toluca Lake.

Child star Macaulay Caulkin and fiancée Brenda Song stepped out with their two children and family members in the same Toluca Lake neighborhood before quickly retreating to their gated home.

Song, best known for her starring role as London Tipton in The Suite Life of Zack & Cody, rocked a sexy witch costume while her partner was dressed as the clown from It.

Across the country, Ratajkowski took her son Sylvester trick-or-treating in a playful monochrome red look.

Her two-year-old blonde boy, who she affectionately calls “Sly,” was dressed in an iridescent purple and blue octopus costume.

The toddler enjoyed a blue lollipop while his beautiful mother anchored his legs with her hands.

The brunette bombshell was dressed in a knee-length hooded coat with fringe and she wore a red pipe cleaner headband with glued-on eyes.

The supermodel’s rich brunette hair was styled in a center parting, two low-hanging braids and curtain bangs.

Halloween – which takes place on October 31st every year – fell on a Tuesday evening this year.

Halloween or Hallowe’en is a festival celebrated on the eve of the Western Christian festival of All Saints’ Day.

It begins with the celebration of Allhallowtide, the time in the liturgical year dedicated to remembering the dead, including saints, martyrs and all the faithful departed.

On social media, celebrities were quick to post images of their recent celebrations, costumes and decorations.

Most of the stars received an A for creativity for ignoring SAG-AFTRA’s warning not to dress up as movie characters during the ongoing strike.
