Prince Harry and Meghan Markle have been captured taking their two costume-clad kids Prince Archie and Princess Lilibet trick-or-treating in Montecito.

Royal commentator and biographer Angela Levin says Meghan Markle will be “absolutely furious” at Family Guy for mocking her and Prince Harry in an episode poking fun at the couple.

“Harry couldn’t care less, but he doesn’t like her upset,” she told Sky News host Paul Murray.

“She can’t understand why people don’t realise that she’s a global, wonderful leader for us all.

“Instead of which people see right through her and make fun of her.”

Family Guy, an American sitcom, has mocked Meghan Markle and Prince Harry’s Netflix deal in the latest episode titled: ‘A Stache from the Past’.

The Duke and Duchess were also spoofed in an episode of the popular TV show ‘South Park’ earlier this year in February.

In a video filmed by a fellow trick-or-treater and posted to social media, the family-of-four were seen walking down a tree-lined street with their backs to the camera.

Prince Harry donned a black cap, black pants, a grey sweatshirt and white sneakers.

The 39-year-old was spotted adorably holding his four-year-old son’s hand and carrying Lilibet’s candy bucket.

Archie was dressed in a black and white costume, suspected to be a skeleton, which he paired with white shoes. He was holding his own Halloween pail.

Meghan Markle was dressed casually in a black cap, black t-shirt, navy blue pants, white sneakers and accessorised with a cream tote bag.

The former Suits actress was carrying her two-year-old daughter, who was dressed in a billowing pink costume.

The royal couple first celebrated the spooky holiday together in 2016 at a Toronto Halloween party with Harry’s cousin Princess Eugenie.

Meghan donned a vintage pilot cap and goggles while Harry wore a bandana and a gas mask.

Reflecting on the party in their Netflix docuseries, Harry explained the gathering happened just before they went public with their relationship.

Not wanting to tip the tabloids off before they were ready, they deliberately chose outfits that would disguise their identities.

“We went to this Halloween party where we could be completely dressed up and no one would know. I had a bandana and goggles,” Harry said.
