What happens in Cabo...inevitably makes its way onto Instagram. Lauren Conrad gave fans a glimpse of her bachelorette bash in Cabo San Lucas, Mexico, this weekend, when she and BFF Lo Bosworth posted photos from their girls' getaway online.

The bride-to-be shared multiple pictures on Saturday, June 21, and Sunday, June 22, including one shot of herself admiring the view from a balcony. In the pic, Conrad, 28, stands with her back to the camera, a big white bow perched atop her head as she gazes out at the palm trees and picturesque pool. The caption reads: "Good morning... #DontTellMrTell." (Mr. Tell is William Tell, the former Hills star's fiance.)

Another photo posted to her account the next day shows her sitting on the beach, facing the ocean, with two pals. "Tres amigas," she wrote alongside the image. "#Don'tTellMrTell." 

Bosworth got in on the fun, too, Instagramming a group shot of herself with Conrad and four other friends on a night out in Mexico. As in the first picture, the future Mrs. Tell is rocking a big Minnie Mouse-style white bow in her hair.

Bosworth also shared a photo of some festive temporary tattoos the girls got in honor of their BFF's big weekend. The ink reads: "I belong with Lauren's Bachelorette Party. If I'm lost, please buy me a drink." 

The Paper Crown designer has been engaged to ex-Something Corporate rocker Tell since last October. "I had no idea it was coming," she told Cosmopolitan in January. "He didn't even ask my friends [about the ring], which was a bold move. He said, 'I know you, and I know what you like.' And I love it. It's perfect."
