Gwyneth’s celebrity pals planning wild bachelorette party in Mexico

Gwyneth Paltrow has said she’s looking forward to her “first” wedding to producer Brad Falchuk, because she eloped with ex-husband, rocker Chris Martin.

And it seems it will include a wild VIP bachelorette party this weekend in Mexico.

Sources exclusively told Page Six on Wednesday that Paltrow’s pals — including Cameron Diaz and designer Stella McCartney — were headed south of the border for the bash before Paltrow and Falchuck get hitched.

A source said that Diaz booked a private jet for 12 guests to head down to the party. (We can only imagine the activities, as Paltrow’s site Goop is famous for suggesting vagina steams and sex-boosting jade eggs.)

Earlier this year, Paltrow told People of the nuptials: “I’m excited about everything! I’ve never had a wedding before . . . So even though I’m 45, I sort of feel like a 21-year-old.”

She added of the planning: “It’s kind of fun to talk about with my girlfriends. They send me pictures of dresses — they’re as excited about it as I am.”

Paltrow’s famous friends include Reese Witherspoon, Drew Barrymore, Beyoncé and Kate Hudson.

Reps did not get back to us.

Paltrow and Falchuck announced that they were engaged in a “Sex & Love” issue of her Goop magazine.
