Sara Foster says she didn’t sign an NDA to attend Jeff Bezos and Lauren Sanchez‘s “intimate” wedding … but, that doesn’t mean she’s spilling the tea about it — keeping mum about secret guests she claims weren’t photographed.

The actress was chatting with her sis on “The World’s First Podcast with Erin & Sara Foster” earlier this week, during which Erin revealed she tried to call Sara multiple times during the festivities … and, she never got a call back.

Erin asks for all the tea … but, Sara just says the wedding was a very personal affair — adding she doesn’t get all the online hate about a group of people just attending a wedding.

As you know … we already knew about a ton of stars who showed up to support Sanchezos — including Kylie Jenner and her sister Kendall, Brooks Nader, Leonardo DiCaprio, Oprah, Orlando Bloom, Tom Brady and Sydney Sweeney.

Jeff and Lauren — who is going by Lauren Sanchez Bezos now — got married on a Friday … but the whole week was full of events celebrating the duo, including a good old-fashioned PJ party.

Attendees weren’t allowed to bring their phone to some events … and, many haven’t spoken about exactly what they did throughout the wedding week.
