Here Comes the Bridesmaid: Kirsten Dunst Hosts BFF's Bachelorette Party

Actress organizes a killer ladies weekend for five pals in Mexico in the wake of battling engagement rumors of her own

With friends like these, who needs travel agents? Or wedding planners, for that matter.

Kirsten Dunst was a best friend par excellence this week, when she hosted a bachelorette party for her BFF since childhood (and frequent red carpet companion) Molly and four of their gal pals in Mexico's St. Regis Punta Mita Resort.

"Being a maid-of-honor...not too shabby!" she tweeted, along with photos of her stay.

We'll say. The three-day fiesta to say adios to singlehood read like a four-star brochure, with the gaggle of girls indulging in yoga on the beach, champagne dinners, a special BBQ on the terrace of their presidential suite, custom massages and being serenaded to live music from a Mexican quartet.

And, of course, ample time for some beach lounging—and seeing as it was a girls-only weekend, there was no sign of Kirsten's paramour (and subject of recent engagement rumors of his own) Garrett Hedlund. Viva la vacation!
