Gwyneth Paltrow Arrives in Mexico for Her Bachelorette Party With Friends

Gwyneth Paltrow in Cabo, Mexico

The 45-year-old actress and her fiance kept their engagement secret for more than a year, revealing it in November.

Gwyneth Paltrow has arrived in Cabo, Mexico, ET has learned, and is ready to party with close friends for her bachelorette party!

The 45-year-old actress has been engaged to writer-director Brad Falchuk for more than a year, but news only trickled out in November. The couple didn't publicly acknowledge it until January. But with the cat out of the bag, Paltrow seems like she's planning to have some fun with it all.

“She looked ecstatic," a source told People on Thursday."They have many fun activities planned, including pool time, spa and fun dinners.”

Among the friends arriving with her was Cameron Diaz, the outlet reported.

Another source told E! News that fashion designer Stella McCartney was there and plans for the week-long celebration would include time at the beach and spa as well as some fabulous dinners out with friends.

The couple has kept it low-key since they went public with their engagement. They released a joint statement at the time, saying, "We feel incredibly lucky to have come together at this juncture in our lives when our collective successes and failures can serve as building blocks for a healthy and happy relationship."

Paltrow has also said she's not going to go overboard with the wedding. She told ET in January that she feels like she's "gotta dial it back."

“I think I'm [too] old to have a big wedding and a big ole white dress and all that,” she said.

The couple hasn't publicly announced their wedding date yet.
