There’s only one thing standing between Jessica Biel and a dream wedding to boyfriend Justin Timberlake, the former boybander’s mother, Lynn Harless.

Mama Timberlake does not get along well with the former star of 7th Heaven and Justin has decided to hold off on any plans to marry Jess until the two leading ladies in his life can connect, The National Enquirer reports.

“It’s created a huge dilemma for Justin,” an Enquirer spy reveals. “He loves Jessica and has every intention of marrying her, but he also adores his mom and doesn’t want t cause any waves with her.”

While Lynn thinks 27 year-old Justin is “too young” to tie the knot, Jessica’s main grip with Lynn is her inability to leave the young couple alone. Jessica feels Lynn is too heavily involved in Justin’s private life:

“Lynne is often at Justin’s home, where she insists on doing his laundry and overseeing what Jessica is cooking. She even made an appearance while Justin and Justin were having a romantic dinner.”
