The National Enquirer reports that Justin Timberlake is so much of a mommy’s boy that it’s preventing him from proposing to his longterm girlfriend, Jessica Biel. Apparently Jessica and Justin’s manager mom don’t get along and his mom is hanging around so much that it’s an issue. Justin’s mom still does his laundry and she often goes out with the couple. Jessica has told her beau to loosen his mommy’s apron strings, and that doesn’t sit well with his mother, who is telling him not to marry her.

Jessica let it be known to Lynn [Justin’s mom] that she was around too much, and that didn’t sit well at all with Justin’s mom, said the pal.

The blowup could not have come at a worse time.

As the Enquirer reported in June, the 27-year-old singer has hinted to friends that he planned to propose to Jessica, 26, before the end of the summer. He’s been checking out princess-cut diamond engagement rings at high-end jeweler Harry Winston.

“But Lynn thinks her son is too young to marry,” his pal said.

“Lynn is often at Justin’s home, where she insists on doing his laundry and overseeing what Jessica is cooking. She even made an appearance at Pace restaurant on June 10 while Justin and Jessica were having a romantic dinner.

“It’s created a huge dilemma for Justin.

“He is completely in love with Jessica and has every intention of marrying her, but he also adores his mom and doesn’t want to cause any waves with her.”

Now insiders say that Justin will hold off on making any wedding plans until Jessica and his mom call a truce.

If Justin’s mom gets on Jessica’s nerves now it’s only going to get much worse if they get married. I love my mother in law, but she still tries to do everything for my husband as if he’s a child. She mends my clothing without asking, does all the laundry, irons everything, folds and puts it away, and this is when she’s at my house. If I tell her not to do something, she’ll start crying and say she’s only trying to help. I have never been able to ask her not to do something without it resulting in her sobbing. Don’t get me wrong, I appreciate her helping out but there’s no way you can give her any kind of feedback. Still, I think whichever problems I have with my MIL are minor compared to what many wives face.

It sounds like Justin, not Jessica, is the one who should be telling his mom to back off. He probably likes the arrangement though because he has someone to do his laundry and clean his house. He’s rich enough to hire someone and tell his mom he’ll visit her on his schedule, though.
