The 46-year-old actress is expected to marry Brad Falchuk at her home in the Hamptons on Saturday night, a source tells ET. The pair's rehearsal dinner will take place at Jerry and Jessica Seinfeld's home.
According to the source, Paltrow's home underwent a lot of work last year, and she had some gardening projects done over the summer. ET's source says the property is completely private and secluded, with no vantage point from the road or anywhere public. Paltrow, Falchuk and their guests will therefore be able to enjoy the intimate event away from prying eyes.
A separate source tells ET that the Hamptons is one of Paltrow's "favorite places on Earth."
"They have been planning this wedding all year," the source reveals, adding that the actress has "worked incredibly hard to keep their wedding a secret."
"Gwyneth pays attention to every details so we are all set for a fairytale wedding," the source declares. Expected to be in attendance are A-listers like Cameron Diaz and Robert Downey Jr., while Paltrow's mom, Blythe Danner, is already there to help her prepare for the big day.
The Iron Man star's kids, Apple and Moses, whom she shares with ex Chris Martin, will also be involved. "Gwyneth has included her kids in some of the planning and they can’t wait. They adore Brad and are excited for their mom," ET's source says. "Brad will be a wonderful husband to Gwyneth because he truly grounds her in every way."

While speaking with ET in January, the actress admitted it took her a while to overcome her fear of intimacy and be able to take the next step with Falchuk.
“It’s a life-long project,” she confessed. “I think that there are certain people who have a really hard time with intimacy. I always say, I'm a good sister. I'm a good daughter. I'm a good girlfriend. I'm a good mother. That romantic slice of the pie chart of my life has always been where I find my deepest work... I just am trying to towards intimacy instead of being scared of it and I'm really lucky that I found a partner that's patient and loves me and is willing to help me with my process.”
And while Paltrow noted that she’s too ”busy” to have started wedding planning just yet, she did give us a few hints.
“I think I'm [too] old to have a big wedding and a big ole white dress and all that,” she said. “I gotta dial it back.”
