What did Wallis Day claim in her Instagram stories?

In May, Day shared a series of Instagram stories containing allegations about Guo and their relationship.

One post claimed that Guo refused to let emergency services into her residence to help a dying person because there were drugs inside the property.

“Watch out guys, this person refused to let EMS into their house when someone was dying because they had drugs everywhere #narcissist,” Day’s story said, according to a screenshot included in Guo’s court filing.

Day also claimed that Guo wanted her to sign a prenuptial agreement, that she once came home drunk and wanted to have sex, and that she stole “hundreds of thousands” of Day’s belongings to pressure her into signing a nondisclosure agreement (NDA).

When were Instagram Stories released?

According to court documents, Guo and Day dated from July 2025 to February 2026. Day made the allegations public in May, when she had approximately 4.3 million followers on Instagram.

The posts and their reported reach have now become central to Guo’s request for information from Meta.

What does Lucy Guo claim?

In her affidavit, Guo described Day’s posts as “full of lies”.

She said her planned defamation suit against Day would focus on what she called “the most offensive statement” — the allegation that she refused to let emergency services into her home.

“I never refused to let the emergency services into my house to help anyone, let alone when someone was dying,” Guo said in her affidavit.

What information does Lucy Guo want from Meta?

Guo is looking for entries that could ensure the reach and spread of Day’s Instagram Story.

In her request, she asks Meta to reveal when the story was posted and removed, who may have viewed it, and how many times it was viewed, liked, shared and reposted.

It also looks for information on the number of followers of both women before and after the post.

The data could help determine the extent to which the allegations spread on Instagram as Guo prepares his proposed defamation case in the UK.

The San Francisco Standard and The California Post reached out to Guo for comment but did not receive a response.
