Lauren Conrad Bachelorette Party: 'The Hills' Star Heads To Mexico With Friends

Lauren Conrad headed to Mexico this week for her bachelorette celebration in Cabo San Lucas.

Joined by former Hills co-star, Lo Bosworth, and friends Hannah Skvarla and Jilli Hendrix, Conrad ventured south of the border on Thursday for some pre-wedding fun.

"Let the games begin… #donttellmrtell," Conrad teased on Instagram, according to a June 20 report by PEOPLE Magazine. In the accompanying photo, Conrad showed off her view, which included a banner of confetti. In a second photo, a ring-shaped cookie that read, "Lauren's Bachelorette," was seen.

Conrad and her fiance, William Tell, began dating in Feb. 2012 after being set up by mutual friends, and became engaged in Oct. 2013. At the time of their engagement, Conrad took to her blog where she told fans she was "very excited" and "beyond thrilled." Ever since the engagement, Conrad has been planning for the perfect wedding -- and sharing the process on her blog.

Tell, the former guitarist and backing vocalist for the group Something Corporate, has also been a part of the planning process -- especially since graduating from law school this past May.

"[Tell] will have a lot to do with the music," a source explained to Us Weekly in Nov. 2013. "She wants Will to share his opinions. She's not going to be a bridezilla!"

According to a Feb. 2014 report by In Touch Weekly, Conrad and Tell have set a wedding date for this fall.

"She’s designing the entire thing herself, including her wedding dress,” In Touch's insider added. “She’s so excited to see her vision come to life.”
