Former Hills star Lauren Conrad has established a few rules to ensure her upcoming wedding to fiance' William Tell is free of drama.

A friend of the former reality star slipped that there will not be a Hills reunion with her former cast members. Conrad will not invite them, including Heidi Montag and Spencer Pratt, or any of her ex-boyfriends that appeared on the show. 

"Inviting everyone she's ever worked with is also a no-no," a friend told Life & Style. "She doesn't want any drama."

The only Laguna Beach and Hills co-star Conrad has invited is her good friend Lo Bosworth, who will actually be one of her bridesmaids

The source revealed that in an attempt to control what gets leaked to the media on her special day, Conrad is also considering banning cellphones on the premises at her wedding location. 

"She wants to control how information gets out," her friend told the weekly. "She's even thinking of banning cell phones from the ceremony!"

Conrad, who is known for her great personal style and creative background, will recruit a wedding planner, but will not allow them to have full control over her nuptials.

"She'll definitely get someone to help her out with the planning, but she isn't going to give control over to anyone else," explains the friend.

Conrad began dating Tell on Valentine's Day in 2012. She announced their engagement on Oct. 13. The couple moved into her condo in Los Angeles' Brentwood neighborhood before he asked her hand in marriage.

Conrad made her reality show debut on Laguna Beach: The Real OC in 2004. She later appeared in her own spinoff series, The Hills. The second reality show followed her internship at Teen VOGUE  and Seventeen magazines in Los Angeles. 

The Hills also followed her dating life with several boyfriends, including Brody Jenner. Her feud with Montag and Pratt continued, even after the couple allegedly leaked a sex tape featuring Conrad with her ex Jason Wahler.
